Struct Encoder 

pub struct Encoder { /* private fields */ }

Builder for encoding multiple values into a byte stream.

Encoder provides a convenient API for serializing complex types by chaining method calls. All integers are encoded in little-endian format.

Example

let mut enc = Encoder::with_capacity(64);
enc.push_u64(42);
enc.push_string("hello");
enc.push_bool(true);
enc.push_bytes(&[1, 2, 3]);

let bytes = enc.into_vec();

Implementations

impl Encoder

pub fn new() -> Self

Creates a new empty encoder.

pub fn with_capacity(capacity: usize) -> Self

Creates a new encoder with pre-allocated capacity.

Use this when you know the approximate size to avoid reallocations.

pub fn push_u8(&mut self, value: u8)

Appends a u8 value.

pub fn push_u16(&mut self, value: u16)

Appends a u16 value (little-endian).

pub fn push_u32(&mut self, value: u32)

Appends a u32 value (little-endian).

pub fn push_u64(&mut self, value: u64)

Appends a u64 value (little-endian).

pub fn push_u128(&mut self, value: u128)

Appends a u128 value (little-endian).

pub fn push_bool(&mut self, value: bool)

Appends a boolean value (0 or 1).

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

Appends raw bytes without length prefix.

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

Appends a byte slice with a u32 length prefix.

Format: [length: u32][data: bytes]

pub fn push_string(&mut self, value: &str)

Appends a string with a u32 length prefix.

The string is encoded as UTF-8 bytes.

pub fn push_codec<T: BytesCodec>(&mut self, value: &T)

Appends a value that implements BytesCodec with a length prefix.

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

Returns the encoded bytes as a slice.

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

Consumes the encoder and returns the encoded bytes.

Trait Implementations

impl Clone for Encoder

fn clone(&self) -> Encoder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Encoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Encoder

fn default() -> Encoder

Returns the “default value” for a type.
