Struct EventChannelQuery 

pub struct EventChannelQuery {
    pub namespace: Option<String>,
    pub component: Option<String>,
    pub topic: Option<String>,
}

Unified query for event channels with optional scope filters

Fields

namespace: Option<String>

Optional namespace filter

component: Option<String>

Optional component filter (requires namespace to be meaningful)

topic: Option<String>

Optional topic filter (requires namespace and component to be meaningful)

Implementations

impl EventChannelQuery

pub fn all() -> Self

Query all event channels (no filters)

pub fn namespace(namespace: impl Into<String>) -> Self

Query event channels in a specific namespace

pub fn component( namespace: impl Into<String>, component: impl Into<String>, ) -> Self

Query event channels for a specific component

pub fn topic( namespace: impl Into<String>, component: impl Into<String>, topic: impl Into<String>, ) -> Self

Query event channels for a specific topic

pub fn scope_level(&self) -> u8

Get the scope level (0=all, 1=namespace, 2=component, 3=topic)

Trait Implementations

impl Clone for EventChannelQuery

fn clone(&self) -> EventChannelQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventChannelQuery

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

Formats the value using the given formatter.

impl Hash for EventChannelQuery

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 EventChannelQuery

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