Enum QueueError 

pub enum QueueError {
    ThreadSpawn(ThreadSpawnError),
    ChannelClosed,
    SendTimedOut {
        after: Duration,
    },
}

Errors specific to Queue. Converts into the crate-wide Error via ? (see crate::error::Error).

Variants

ThreadSpawn(ThreadSpawnError)

The operating system could not create the queue’s worker thread.

Construction returns without retaining the supplied downstream sink.

ChannelClosed

The worker has exited and can no longer receive media buffers.

A queue does not restart its worker; stop or rebuild the owning pipeline.

SendTimedOut

OverflowPolicy::Block only — the channel stayed full for the whole after, meaning whatever’s downstream of this Queue didn’t just fall behind (ordinary, self-resolving backpressure), it’s genuinely stuck. Unlike OverflowPolicy::DropNewest’s silent, expected-under-load BusEvent::Dropped, this is surfaced as a real error precisely because it isn’t expected — see OverflowPolicy::Block’s own docs.

Fields

after: Duration

Maximum time spent waiting for free capacity before the current buffer was returned to the caller as undelivered.

Trait Implementations

impl Debug for QueueError

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

Formats the value using the given formatter.

impl Display for QueueError

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

Formats the value using the given formatter.

impl Error for QueueError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<QueueError> for Error

fn from(source: QueueError) -> Self

Converts to this type from the input type.

impl From<ThreadSpawnError> for QueueError

fn from(source: ThreadSpawnError) -> Self

Converts to this type from the input type.
