Struct ChannelKey 

pub struct ChannelKey { /* private fields */ }

Canonical key describing a channel’s schema and attachments.

Implementations

impl ChannelKey

pub fn new( schema: SchemaId, backpressure: Backpressure, producers: impl Iterator<Item = EndpointId>, consumers: impl Iterator<Item = EndpointId>, ) -> Self

Create a new channel key from producers and consumers.

pub fn contains( &self, schema: SchemaId, backpressure: Backpressure, producer: EndpointId, consumer: EndpointId, ) -> bool

Check whether this key matches the supplied endpoints and schema.

pub fn is_compatible(&self, desired: &ChannelKey) -> bool

Check whether the key is compatible with another key.

pub fn schema(&self) -> SchemaId

Return the schema identifier for the key.

pub fn backpressure(&self) -> Backpressure

Return the backpressure behaviour for this channel.

pub fn producers(&self) -> &[EndpointId]

Return producers on this channel.

pub fn consumers(&self) -> &[EndpointId]

Return consumers on this channel.

Trait Implementations

impl Clone for ChannelKey

fn clone(&self) -> ChannelKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelKey

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

Formats the value using the given formatter.

impl Hash for ChannelKey

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 ChannelKey

fn cmp(&self, other: &ChannelKey) -> 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 ChannelKey

fn eq(&self, other: &ChannelKey) -> 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 ChannelKey

fn partial_cmp(&self, other: &ChannelKey) -> 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.
