Struct Frame 

pub struct Frame {
    pub seq: u64,
    pub kind: FrameKind,
    pub bytes: Bytes,
}

One numbered frame, already encoded.

The bytes are built once, when the frame is numbered, and the buffer keeps them: a replay is neither a re-encode nor a copy, and two consumers reading the same frame are guaranteed the same bytes.

They are [Bytes] rather than a Vec<u8> because every consumer sending a frame holds it while the socket write is under way. As a Vec<u8> each of those is a copy. Cloning Bytes bumps a refcount instead, and axum’s Message::Binary takes one, so the frame reaches the socket without ever being copied.

Fields

seq: u64

Where this frame sits in the stream.

kind: FrameKind

Which message type it carries.

bytes: Bytes

Header and body, concatenated, as they go on the wire.

Trait Implementations

impl Clone for Frame

fn clone(&self) -> Frame

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Frame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Frame

fn eq(&self, other: &Frame) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
