tl-proto 0.3.6

tl-proto  

A collection of traits for working with TL serialization/deserialization.

Example

/* my_proto.tl */

int ? = Int;
string ? = String;
bytes data:string = Bytes;

int256 8*[ int ] = Int256;

pub.ed25519 key:int256 = PublicKey;
pub.aes key:int256 = PublicKey;
pub.overlay name:bytes = PublicKey;

NOTE: TL scheme is parsed by tl-scheme crate at compile time.

use tl_proto::{TlRead, TlWrite};

#[derive(TlRead, TlWrite)]
#[tl(size_hint = 32)]
struct HashRef<'tl>(&'tl [u8; 32]);

#[derive(TlRead, TlWrite)]
#[tl(boxed, scheme = "my_proto.tl")]
enum PublicKey<'tl> {
    #[tl(id = "pub.aes")]
    Aes { key: HashRef<'tl> },

    #[tl(id = "pub.ed25519", size_hint = 32)]
    Ed25519 { key: HashRef<'tl> },

    #[tl(id = "pub.overlay")]
    Overlay { name: &'tl [u8] },
}

#[derive(TlRead, TlWrite)]
#[tl(boxed)]
enum Address<'tl> {
    #[tl(id = 0x670da6e7)]
    Udp { ip: i32, port: i32 },

    #[tl(id = 0xe31d63fa)]
    Udp6 { ip: &'tl [u8; 16], port: i32 },

    #[tl(id = 0x092b02eb)]
    Tunnel {
        to: HashRef<'tl>,
        pubkey: PublicKey<'tl>,
    },
}

fn main() {
    assert_eq!(PublicKey::TL_ID_AES, 0x2dbcadd4);
    
    let bytes = tl_proto::serialize(&Address::Udp {
        ip: 123,
        port: 3000,
