RlpDecodeErrors

Set of errors while performing RLP decoding.

error{ UnexpectedValue, InvalidEnumTag, LengthMissmatch, Overflow } || Allocator.Error

DecodeRlp

RLP decoding wrapper function. Encoded string must follow the RLP specification.

Supported types:

• bool
• int
• enum, enum_literal
• null
• ?T
• [N]T array types.
• []const T slices.
• structs. Both tuple and non tuples.

All other types are currently not supported.

Signature

pub fn decodeRlp(comptime T: type, allocator: Allocator, encoded: []const u8) RlpDecodeErrors!T

RlpDecoder

RLP Decoder structure. Decodes based on the RLP specification.

Properties

struct {
  /// The RLP encoded slice.
  encoded: []const u8
  /// The position into the encoded slice.
  position: usize
}

Init

Sets the decoder initial state.

Signature

pub fn init(encoded: []const u8) RlpDecoder

AdvancePosition

Advances the decoder position by new size.

Signature

pub fn advancePosition(self: *RlpDecoder, new: usize) void

Decode

Decodes a rlp encoded slice into a provided type. The encoded slice must follow the RLP specification.

Supported types:

• bool
• int
• enum, enum_literal
• null
• ?T
• [N]T array types.
• []const T slices.
• structs. Both tuple and non tuples.

All other types are currently not supported.

Signature

pub fn decode(self: *RlpDecoder, comptime T: type, allocator: Allocator) RlpDecodeErrors!T
