pub enum Opcode {
    Continuation,
    Text,
    Binary,
    Close,
    Ping,
    Pong,
    Reserved(u8),
}

Opcode (RFC 6455 §5.2, S. 28-29) — 4-bit, definiert Interpretation der Payload.

Spec-Werte:

• 0x0 — Continuation
• 0x1 — Text Frame (UTF-8)
• 0x2 — Binary Frame
• 0x3-0x7 — Reserved Non-Control
• 0x8 — Connection Close
• 0x9 — Ping
• 0xA — Pong
• 0xB-0xF — Reserved Control

Variants

Continuation

0x0 — Continuation frame.

Text

0x1 — Text frame (UTF-8).

Binary

0x2 — Binary frame.

Close

0x8 — Connection-Close frame.

Ping

0x9 — Ping frame.

Pong

0xA — Pong frame.

Reserved(u8)

0x3-0x7 reserved non-control / 0xB-0xF reserved control.

Implementations

impl Opcode

pub const fn from_bits(v: u8) -> Self

Konvertiert vom Wire-Wert (4-bit).

pub const fn to_bits(self) -> u8

Wire-Wert (4-bit).

pub const fn is_control(self) -> bool

Spec §5.5 — Control Frames sind opcodes 0x8-0xF. Sie haben folgende Eigenschaften: payload <= 125 bytes (Spec §5.5), duerfen nicht fragmentiert werden (FIN=1).

Trait Implementations

impl Clone for Opcode

fn clone(&self) -> Opcode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Opcode

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

Formats the value using the given formatter.

impl Hash for Opcode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Opcode

fn eq(&self, other: &Opcode) -> 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.
