Struct DecodedFrame 

#[non_exhaustive]
pub struct DecodedFrame {
    pub offset: u64,
    pub argv: Argv,
}

A decoded mutation frame the replica should apply to its local store. Ownership of the Argv passes to the caller.

use kevy_replicate::replica::DecodedFrame;
use kevy_replicate::wire::{decode_frame, encode_frame};

let argv = kevy_resp::Argv::from(vec![b"SET".to_vec(), b"k".to_vec(), b"v".to_vec()]);
let (frame, _) = decode_frame(&encode_frame(3, &argv))?;
assert_eq!(frame, DecodedFrame::new(3, argv));

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

offset: u64

Monotonic offset the primary assigned at apply-time.

use kevy_replicate::wire::{decode_frame, encode_frame};

let ping = kevy_resp::Argv::from(vec![b"PING".to_vec()]);
let (frame, _) = decode_frame(&encode_frame(41, &ping))?;
assert_eq!(frame.offset, 41);

argv: Argv

Wire-decoded argv — feed to the dispatcher the same way AOF replay does (cmd name + arg bytes).

use kevy_replicate::wire::{decode_frame, encode_frame};

let del = kevy_resp::Argv::from(vec![b"DEL".to_vec(), b"k".to_vec()]);
let (frame, _) = decode_frame(&encode_frame(0, &del))?;
assert_eq!(frame.argv.first(), Some(&b"DEL"[..]));
assert_eq!(frame.argv.get(1), Some(&b"k"[..]));

Implementations

impl DecodedFrame

pub fn new(offset: u64, argv: Argv) -> Self

The frame at offset carrying argv.

let frame = DecodedFrame::new(7, kevy_resp::Argv::from(vec![b"DEL".to_vec(), b"k".to_vec()]));
assert_eq!(frame.offset, 7);
