pub struct Encoder { /* private fields */ }

Binary TLV encoder.

Implementations

impl Encoder

pub fn new() -> Self

Creates a new empty encoder.

pub fn with_capacity(cap: usize) -> Self

Creates an encoder with pre-allocated capacity.

pub fn finish(self) -> Vec<u8>

Returns the encoded bytes, consuming the encoder.

pub fn as_slice(&self) -> &[u8]

Returns the encoded bytes as a slice.

pub fn clear(&mut self)

Clears the buffer for reuse.

pub fn len(&self) -> usize

Returns current length.

pub fn is_empty(&self) -> bool

Returns true if empty.

pub fn u64(&mut self, v: u64)

Encodes a u64 as tagged varint.

pub fn bytes(&mut self, b: &[u8])

Encodes raw bytes with length prefix.

pub fn str(&mut self, s: &str)

Encodes a UTF-8 string with length prefix.

pub fn cid32(&mut self, cid: &Cid32)

Encodes a 32-byte CID (no length prefix, fixed size).

pub fn public_key(&mut self, pk: &PublicKeyBytes)

Encodes a 32-byte public key (no length prefix, fixed size).

pub fn signature(&mut self, sig: &SignatureBytes)

Encodes a 64-byte signature (no length prefix, fixed size).
