Function bcs::from_bytes

pub fn from_bytes<'a, T>(bytes: &'a [u8]) -> Result<T>
where
    T: Deserialize<'a>,

Deserializes a &[u8] into a type.

This function will attempt to interpret bytes as the BCS serialized form of T and deserialize T from bytes.

Examples

use bcs::from_bytes;
use serde::Deserialize;

#[derive(Deserialize)]
struct Ip([u8; 4]);

#[derive(Deserialize)]
struct Port(u16);

#[derive(Deserialize)]
struct SocketAddr {
    ip: Ip,
    port: Port,
}

let bytes = vec![0x7f, 0x00, 0x00, 0x01, 0x41, 0x1f];
let socket_addr: SocketAddr = from_bytes(&bytes).unwrap();

assert_eq!(socket_addr.ip.0, [127, 0, 0, 1]);
assert_eq!(socket_addr.port.0, 8001);
