Function bcs::to_bytes

pub fn to_bytes<T>(value: &T) -> Result<Vec<u8>>
where
    T: ?Sized + Serialize,

Serialize the given data structure as a Vec<u8> of BCS.

Serialization can fail if T’s implementation of Serialize decides to fail, if T contains sequences which are longer than MAX_SEQUENCE_LENGTH, or if T attempts to serialize an unsupported datatype such as a f32, f64, or char.

Examples

use bcs::to_bytes;
use serde::Serialize;

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

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

#[derive(Serialize)]
struct Service {
    ip: Ip,
    port: Vec<Port>,
    connection_max: Option<u32>,
    enabled: bool,
}

let service = Service {
    ip: Ip([192, 168, 1, 1]),
    port: vec![Port(8001), Port(8002), Port(8003)],
    connection_max: Some(5000),
    enabled: false,
};

let bytes = to_bytes(&service).unwrap();
let expected = vec![
    0xc0, 0xa8, 0x01, 0x01, 0x03, 0x41, 0x1f, 0x42,
    0x1f, 0x43, 0x1f, 0x01, 0x88, 0x13, 0x00, 0x00,
    0x00,
];
assert_eq!(bytes, expected);
