-// Decode parses RLP-encoded data from r and stores the result in the

-// not implement ByteReader, Decode will do its own buffering.
-//
-// Decode uses the following type-dependent decoding rules:
-//
-// If the type implements the Decoder interface, decode calls
-// DecodeRLP.
-//
-// To decode into a pointer, Decode will decode into the value pointed
-// to. If the pointer is nil, a new value of the pointer's element
-// type is allocated. If the pointer is non-nil, the existing value
-// will be reused.
-//
-// To decode into a struct, Decode expects the input to be an RLP
-// list. The decoded elements of the list are assigned to each public
-// field in the order given by the struct's definition. The input list
-// must contain an element for each decoded field. Decode returns an
-// error if there are too few or too many elements.
-//
-// The decoding of struct fields honours certain struct tags, "tail",
-// "nil" and "-".
-//
-// The "-" tag ignores fields.
-//
-// For an explanation of "tail", see the example.
-//
-// The "nil" tag applies to pointer-typed fields and changes the decoding
-// rules for the field such that input values of size zero decode as a nil
-// pointer. This tag can be useful when decoding recursive types.
-//
-// type StructWithEmptyOK struct {
-// Foo *[20]byte `rlp:"nil"`
-// }
-//
-// To decode into a slice, the input must be a list and the resulting
-// slice will contain the input elements in order. For byte slices,
-// the input must be an RLP string. Array types decode similarly, with
-// the additional restriction that the number of input elements (or
-// bytes) must match the array's length.
-//
-// To decode into a Go string, the input must be an RLP string. The
-// input bytes are taken as-is and will not necessarily be valid UTF-8.
-//
-// To decode into an unsigned integer type, the input must also be an RLP
-// string. The bytes are interpreted as a big endian representation of
-// the integer. If the RLP string is larger than the bit size of the
-// type, Decode will return an error. Decode also supports *big.Int.
-// There is no size limit for big integers.
-//
-// To decode into an interface value, Decode stores one of these
-// in the value:
-//
-// []interface{}, for RLP lists
-// []byte, for RLP strings
+// Decode parses RLP-encoded data from r and stores the result in the value pointed to by
+// val. Please see package-level documentation for the decoding rules. Val must be a
+// non-nil pointer.
//
-// Non-empty interface types are not supported, nor are booleans,
-// signed integers, floating point numbers, maps, channels and
-// functions.
+// If r does not implement ByteReader, Decode will do its own buffering.

+The purpose of RLP (Recursive Linear Prefix) is to encode arbitrarily nested arrays of
+binary data, and RLP is the main encoding method used to serialize objects in Ethereum.
+The only purpose of RLP is to encode structure; encoding specific atomic data types (eg.
+strings, ints, floats) is left up to higher-order protocols. In Ethereum integers must be
+represented in big endian binary form with no leading zeroes (thus making the integer
+value zero equivalent to the empty string).
+
+RLP values are distinguished by a type tag. The type tag precedes the value in the input
+stream and defines the size and kind of the bytes that follow.
+
+# Encoding Rules
+
+Package rlp uses reflection and encodes RLP based on the Go type of the value.
+
+If the type implements the Encoder interface, Encode calls EncodeRLP. It does not
+call EncodeRLP on nil pointer values.
+
+To encode a pointer, the value being pointed to is encoded. A nil pointer to a struct
+type, slice or array always encodes as an empty RLP list unless the slice or array has
+element type byte. A nil pointer to any other value encodes as the empty string.
+
+Struct values are encoded as an RLP list of all their encoded public fields. Recursive
+struct types are supported.
+
+To encode slices and arrays, the elements are encoded as an RLP list of the value's
+elements. Note that arrays and slices with element type uint8 or byte are always encoded
+as an RLP string.
+
+A Go string is encoded as an RLP string.
+
+An unsigned integer value is encoded as an RLP string. Zero always encodes as an empty RLP
+string. big.Int values are treated as integers. Signed integers (int, int8, int16, ...)
+are not supported and will return an error when encoding.
+
+Boolean values are encoded as the unsigned integers zero (false) and one (true).
+
+An interface value encodes as the value contained in the interface.
+
+Floating point numbers, maps, channels and functions are not supported.
+
+# Decoding Rules
+
+Decoding uses the following type-dependent rules:
+
+If the type implements the Decoder interface, DecodeRLP is called.
+
+To decode into a pointer, the value will be decoded as the element type of the pointer. If
+the pointer is nil, a new value of the pointer's element type is allocated. If the pointer
+is non-nil, the existing value will be reused. Note that package rlp never leaves a
+pointer-type struct field as nil unless one of the "nil" struct tags is present.
+
+To decode into a struct, decoding expects the input to be an RLP list. The decoded
+elements of the list are assigned to each public field in the order given by the struct's
+definition. The input list must contain an element for each decoded field. Decoding
+returns an error if there are too few or too many elements for the struct.
+
+To decode into a slice, the input must be a list and the resulting slice will contain the
+input elements in order. For byte slices, the input must be an RLP string. Array types
+decode similarly, with the additional restriction that the number of input elements (or
+bytes) must match the array's defined length.
+
+To decode into a Go string, the input must be an RLP string. The input bytes are taken
+as-is and will not necessarily be valid UTF-8.
+
+To decode into an unsigned integer type, the input must also be an RLP string. The bytes
+are interpreted as a big endian representation of the integer. If the RLP string is larger
+than the bit size of the type, decoding will return an error. Decode also supports
+*big.Int. There is no size limit for big integers.
+
+To decode into a boolean, the input must contain an unsigned integer of value zero (false)
+or one (true).
+
+To decode into an interface value, one of these types is stored in the value:
+
+ []interface{}, for RLP lists
+ []byte, for RLP strings
+
+Non-empty interface types are not supported when decoding.
+Signed integers, floating point numbers, maps, channels and functions cannot be decoded into.
+
+# Struct Tags
+
+As with other encoding packages, the "-" tag ignores fields.
+
+ type StructWithIgnoredField struct{
+ Ignored uint `rlp:"-"`
+ Field uint
+ }
+
+Go struct values encode/decode as RLP lists. There are two ways of influencing the mapping
+of fields to list elements. The "tail" tag, which may only be used on the last exported
+struct field, allows slurping up any excess list elements into a slice.
+
+ type StructWithTail struct{
+ Field uint
+ Tail []string `rlp:"tail"`
+ }
+
+The "optional" tag says that the field may be omitted if it is zero-valued. If this tag is
+used on a struct field, all subsequent public fields must also be declared optional.
+
+When encoding a struct with optional fields, the output RLP list contains all values up to
+the last non-zero optional field.
+
+When decoding into a struct, optional fields may be omitted from the end of the input
+list. For the example below, this means input lists of one, two, or three elements are
+accepted.
+
+ type StructWithOptionalFields struct{
+ Required uint
+ Optional1 uint `rlp:"optional"`
+ Optional2 uint `rlp:"optional"`
+ }
+
+The "nil", "nilList" and "nilString" tags apply to pointer-typed fields only, and change
+the decoding rules for the field type. For regular pointer fields without the "nil" tag,
+input values must always match the required input length exactly and the decoder does not
+produce nil values. When the "nil" tag is set, input values of size zero decode as a nil
+pointer. This is especially useful for recursive types.
+
+ type StructWithNilField struct {
+ Field *[3]byte `rlp:"nil"`
+ }
+
+In the example above, Field allows two possible input sizes. For input 0xC180 (a list
+containing an empty string) Field is set to nil after decoding. For input 0xC483000000 (a
+list containing a 3-byte string), Field is set to a non-nil array pointer.
+
+RLP supports two kinds of empty values: empty lists and empty strings. When using the
+"nil" tag, the kind of empty value allowed for a type is chosen automatically. A field
+whose Go type is a pointer to an unsigned integer, string, boolean or byte array/slice
+expects an empty RLP string. Any other pointer field type encodes/decodes as an empty RLP
+list.
+
+The choice of null value can be made explicit with the "nilList" and "nilString" struct
+tags. Using these tags encodes/decodes a Go nil pointer value as the empty RLP value kind
+defined by the tag.
