Impl functions

decode_type

Returns RLPType from the leading byte with its offset in the array as well as its size.

Arguments

• input - Array of byte to decode

Returns

• (RLPType, offset, size) - A tuple containing the RLPType the offset and the size of the RLPItem to decode

Errors

• empty input - if the input is empty
• input too short - if the input is too short for a given

Fully qualified path: alexandria_encoding::rlp::RLPImpl::decode_type

fn decode_type(input: Span<u8>) -> Result<(RLPType, u32, u32), RLPError>

encode

Recursively encodes multiple a list of RLPItems

Arguments

• input - Span of RLPItem to encode

Returns

• `Span - RLP encoded items as a span of bytes

Errors

• empty input - if the input is empty

Fully qualified path: alexandria_encoding::rlp::RLPImpl::encode

fn encode(mut input: Span<RLPItem>) -> Result<Span<u8>, RLPError>

encode_string

RLP encodes a Array of bytes representing a RLP String.

Arguments

• input - Array of bytes representing a RLP String to encode

Returns

• `Span - RLP encoded items as a span of bytes

Fully qualified path: alexandria_encoding::rlp::RLPImpl::encode_string

fn encode_string(input: Span<u8>) -> Result<Span<u8>, RLPError>

decode

Recursively decodes a rlp encoded byte array as described in https://ethereum.org/en/developers/docs/data-structures-and-encoding/rlp/

Arguments

• input - Array of bytes to decode

Returns

• Span<RLPItem> - Span of RLPItem

Errors

• input too short - if the input is too short for a given
