Struct Encoder

pub struct Encoder { /* private fields */ }

The Encoder struct provides methods for packing values that implement the Packer trait.

Examples

use rust_chain::serializer::{Encoder, Packer};

let mut encoder = Encoder::new(4);
let value = 123u32;

let bytes_written = value.pack(&mut encoder);
assert_eq!(bytes_written, 4);

let packed_bytes = encoder.get_bytes();
assert_eq!(packed_bytes, [123, 0, 0, 0]);

Implementations

impl Encoder

pub fn new(size: usize) -> Self

Constructs a new Encoder with the given initial capacity.

Arguments

• size - The initial capacity of the encoder in bytes.

Returns

A new Encoder instance with the given initial capacity.

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

Returns the packed bytes of this encoder as a byte array.

Returns

A reference to the packed bytes of this encoder as a byte array.

pub fn get_size(&self) -> usize

Returns the number of packed bytes in this encoder.

Returns

The number of packed bytes in this encoder.

pub fn alloc(&mut self, size: usize) -> &mut [u8]

Allocates space in this encoder for packing a value of the given size.

Arguments

• size - The number of bytes to allocate in this encoder.

Returns

A mutable reference to the allocated

pub fn pack<T: Packer>(value: &T) -> Vec<u8>

Packs the given value using the encoder

Arguments

• value - The value to be packed

Examples

use rust_chain::serializer::{Encoder, Packer};

let data = Encoder::pack(&1234u32);
assert_eq!(data, vec![210, 4, 0, 0]);
