Struct Decoder 

pub struct Decoder<'a> { /* private fields */ }

Binary TLV decoder.

Implementations

impl<'a> Decoder<'a>

pub fn new(data: &'a [u8]) -> Self

Creates a new decoder from a byte slice.

pub fn position(&self) -> usize

Returns the current position.

pub fn is_done(&self) -> bool

Returns true if all data has been consumed.

pub fn remaining(&self) -> usize

Returns remaining bytes.

pub fn u64(&mut self) -> Result<u64, BinaryCodecError>

Decodes a tagged u64.

Errors

Returns error if tag mismatch or malformed varint.

pub fn bytes(&mut self) -> Result<&'a [u8], BinaryCodecError>

Decodes tagged bytes.

Errors

• BinaryCodecError::Tag if tag mismatch
• BinaryCodecError::SizeLimit if length exceeds MAX_BYTES_LEN
• BinaryCodecError::Eof if insufficient data

pub fn str(&mut self) -> Result<&'a str, BinaryCodecError>

Decodes a tagged UTF-8 string.

Errors

• BinaryCodecError::Tag if tag mismatch
• BinaryCodecError::SizeLimit if length exceeds MAX_BYTES_LEN
• BinaryCodecError::Eof if insufficient data
• BinaryCodecError::Utf8 if invalid UTF-8

pub fn cid32(&mut self) -> Result<Cid32, BinaryCodecError>

Decodes a 32-byte CID.

Errors

Returns error if tag mismatch or insufficient data.

pub fn public_key(&mut self) -> Result<PublicKeyBytes, BinaryCodecError>

Decodes a 32-byte public key.

Errors

Returns error if tag mismatch or insufficient data.

pub fn signature(&mut self) -> Result<SignatureBytes, BinaryCodecError>

Decodes a 64-byte signature.

Errors

Returns error if tag mismatch or insufficient data.
