Struct serde_bytes::Bytes

#[repr(C)]
pub struct Bytes { /* fields omitted */ }

Wrapper around [u8] to serialize and deserialize efficiently.

use std::collections::HashMap;
use std::io;

use serde_bytes::Bytes;

fn print_encoded_cache() -> bincode::Result<()> {
    let mut cache = HashMap::new();
    cache.insert(3, Bytes::new(b"three"));
    cache.insert(2, Bytes::new(b"two"));
    cache.insert(1, Bytes::new(b"one"));

    bincode::serialize_into(&mut io::stdout(), &cache)
}
