Enum TrySendError 

pub enum TrySendError<T> {
    Closed(T),
    Full(T),
}

Returned by the sync Transport::try_send / Transport::try_send_requests when immediate delivery fails.

The undelivered value T is always returned inside the variant so the caller can recover it without cloning.

Variants and recovery

• Full — the channel is currently at capacity. The message has not been dropped; the caller can retry later with another try_send call, switch to the backpressure-aware send, or discard the message if it is stale.

• Closed — all channel receivers have been dropped. The SiftStream is shutting down. Retrying on the same stream will not succeed.

Variants

Closed(T)

The channel has been closed. The undelivered value is returned.

Full(T)

The channel is currently full. The undelivered value is returned.

Implementations

impl<T> TrySendError<T>

pub fn into_inner(self) -> T

Consume the error, returning the undelivered value.

pub fn is_closed(&self) -> bool

Returns true if this is the Closed variant.

pub fn is_full(&self) -> bool

Returns true if this is the Full variant.

Trait Implementations

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
