PriorityReceiver

Struct PriorityReceiver 

Source
pub struct PriorityReceiver<T> { /* private fields */ }
Expand description

Priority receiver that processes messages by priority

Combines multiple receivers and delivers messages in priority order. Messages with higher priority are processed before lower priority ones.

Implementations§

Source§

impl<T> PriorityReceiver<T>
where T: Send + 'static,

Source

pub fn new() -> Self

Create a new priority receiver with default configuration

Source

pub fn with_config(config: PriorityQueueConfig) -> Self

Create a new priority receiver with custom configuration

Source

pub fn add_source(&mut self, receiver: Receiver<T>, priority: Priority)

Add a message source with the specified priority

§Example
let mut prio_rx = PriorityReceiver::new();

let emergency = ctx.subscribe("/safety/emergency").await?;
prio_rx.add_source(emergency, Priority::Critical);

let telemetry = ctx.subscribe("/sensor/telemetry").await?;
prio_rx.add_source(telemetry, Priority::Low);
Source

pub async fn recv(&mut self) -> Option<(T, Priority)>

Receive the next message in priority order

Returns None when all sources are closed. Returns Some((message, priority)) with the highest priority message available.

§Starvation Prevention

If configured, this method will occasionally process lower-priority messages even when higher-priority messages are available, to prevent starvation.

Source

pub fn stats(&self) -> PriorityQueueStats

Get statistics about the priority queue
