Struct Buffer

Source
pub struct Buffer { /* private fields */ }
Expand description

A buffer for reusing allocations between calls to Buffer::encode and/or Buffer::decode.

use bitcode::{Buffer, Encode, Decode};

let original = "Hello world!";

let mut buffer = Buffer::new();
buffer.encode(&original);
let encoded: &[u8] = buffer.encode(&original); // Won't allocate

let mut buffer = Buffer::new();
buffer.decode::<&str>(&encoded).unwrap();
let decoded: &str = buffer.decode(&encoded).unwrap(); // Won't allocate
assert_eq!(original, decoded);

Implementations§

Source§

impl Buffer

Source

pub fn new() -> Self

Constructs a new buffer.

Source§

impl Buffer

Source

pub fn encode<'a, T: Encode + ?Sized>(&'a mut self, t: &T) -> &'a [u8]

Like encode, but saves allocations between calls.

Source

pub fn decode<'a, T: Decode<'a>>(&mut self, bytes: &'a [u8]) -> Result<T, Error>

Like decode, but saves allocations between calls.
