Struct ChannelTag 

pub struct ChannelTag(pub [u8; 16]);

Sixteen-byte channel tag: a local identity for a channel, wide enough to distinguish channels that a ChannelId cannot.

The two-byte identifier is a hint, and collisions between distinct channel keys are legal — a frame belongs to whichever channel key authenticates it, not to whichever key derives the same identifier. Bookkeeping that has no key at hand to authenticate against therefore needs a wider name; this is that name. Nothing on the wire carries it.

Implementations

impl ChannelTag

pub fn channel_id(&self) -> ChannelId

The channel identifier this tag begins with.

Both come from the same derivation, so the identifier is the tag’s own first two bytes rather than a separate computation.

Trait Implementations

impl Clone for ChannelTag

fn clone(&self) -> ChannelTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelTag

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

Formats the value using the given formatter.

impl Hash for ChannelTag

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 Ord for ChannelTag

fn cmp(&self, other: &ChannelTag) -> 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.

impl PartialEq for ChannelTag

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

impl PartialOrd for ChannelTag

fn partial_cmp(&self, other: &ChannelTag) -> 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

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