Struct StreamChannelSelector 

pub struct StreamChannelSelector {
    pub channel: StreamChannel,
    pub direction: Option<StreamDirection>,
}

Carries the stream channel selector record payload for journal, event, or fixture surfaces. Creating or cloning it only preserves serialized SDK state; append, publish, replay, or export effects are documented on the runtime and port methods that store it.

Fields

channel: StreamChannel

Channel used by this record or request.

direction: Option<StreamDirection>

Optional direction value. When absent, callers should use the documented default or skip that optional behavior.

Implementations

impl StreamChannelSelector

pub fn channel(channel: StreamChannel) -> Self

Builds the channel value with the documented defaults. This is data-only and does not perform I/O, call host ports, append journals, publish events, or start processes.

pub fn matches(&self, delta: &StreamDelta) -> bool

Returns matches for the current value. This is a read-only or data-construction helper unless the method body explicitly calls a port or store.

Trait Implementations

impl Clone for StreamChannelSelector

fn clone(&self) -> StreamChannelSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamChannelSelector

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StreamChannelSelector

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StreamChannelSelector

fn eq(&self, other: &StreamChannelSelector) -> 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 Serialize for StreamChannelSelector

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
