Struct Encoder 

pub struct Encoder { /* private fields */ }

A generic encoder that serializes different primitive types and collections into a byte buffer.

Implementations

impl Encoder

pub fn new() -> Self

Creates a new, empty Encoder.

pub fn push_u8(&mut self, v: u8) -> AzUtilResult<()>

Appends a single u8 value to the buffer.

pub fn push_raw_bytes(&mut self, bytes: Vec<u8>) -> AzUtilResult<()>

Encodes raw bytes by prefixing them with their length and appending them to the buffer.

pub fn push_u16(&mut self, v: u16) -> AzUtilResult<()>

Encodes a u16 value in big-endian format.

pub fn push_u32(&mut self, v: u32) -> AzUtilResult<()>

Encodes a u32 value in big-endian format.

pub fn push_u64(&mut self, v: u64) -> AzUtilResult<()>

Encodes a u64 value in big-endian format.

pub fn push_i64(&mut self, v: i64) -> AzUtilResult<()>

Encodes an i64 value in big-endian format.

pub fn push_usize(&mut self, v: usize) -> AzUtilResult<()>

Encodes a usize value in big-endian format.

pub fn push_opt<T>(&mut self, t: &Option<T>) -> AzUtilResult<()>

where T: Codec,

Encodes an Option<T> by writing a presence flag (1 or 0) followed by the value if present.

pub fn push_slice<T>(&mut self, slice: &[T]) -> AzUtilResult<()>

where T: Codec,

Encodes a slice of T values by prefixing its length and encoding each element.

pub fn push_vec<T>(&mut self, vec: Vec<T>) -> AzUtilResult<()>

where T: Codec + Sized,

Encodes a vector of T values, prefixing each element with its size before encoding it.

pub fn push_string(&mut self, s: &String) -> AzUtilResult<()>

Encodes a UTF-8 string, prefixing it with its length before writing its bytes.

pub fn push_bool(&mut self, b: bool) -> AzUtilResult<()>

Encodes a boolean value as 1 (true) or 0 (false).

pub fn push_i8(&mut self, v: i8) -> AzUtilResult<()>

Encodes an i8 value as a single byte.

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

Consumes the encoder and returns the encoded byte buffer.

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 Default for Encoder

fn default() -> Self

Returns the “default value” for a type.
