Struct ContextId 

pub struct ContextId(/* private fields */);

Available on crate feature masque only.

A CONNECT-UDP Context ID (RFC 9298 §4).

Context ID 0 carries UDP payloads. Non-zero IDs are allocated by extensions (even by the client, odd by the proxy); this crate defines none, so it drops datagrams carrying them.

Implementations

impl ContextId

pub const UDP: ContextId

Context ID 0: UDP payloads.

pub fn new(value: u64) -> Option<ContextId>

A Context ID from its value, if it fits a variable-length integer.

pub fn value(self) -> u64

The raw value.

pub fn is_client_allocated(self) -> bool

Whether the client allocates this ID (non-zero and even).

pub fn is_proxy_allocated(self) -> bool

Whether the proxy allocates this ID (odd).

impl Ord for ContextId

fn cmp(&self, other: &ContextId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ContextId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ContextId

fn partial_cmp(&self, other: &ContextId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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