Stream accounting or lifecycle failure.

Variants

AttemptClosed

The attempt already completed or failed.

BackpressurePending

A new source chunk was offered before the prior chunk was consumed.

NoPendingChunk

A sink advance was reported without pending bytes.

NoSinkObservation

Sink progress was reported without a preflight sink observation.

SinkObservationPending

A second sink observation was started before classifying the first.

NoSourceObservation

A source result was reported without a preflight observation.

SourceObservationPending

A second source observation was started before classifying the first.

InvalidSinkProgress

A sink claimed to accept more than the pending chunk remainder.

ChunkTooLarge

One chunk exceeds the per-operation chunk-size limit.

ChunkLimitExceeded

The stream exceeded its chunk budget.

ObservationLimitExceeded

The stream exceeded its observation budget.

ByteLimitExceeded

Actual or offered bytes exceed the operation limit.

DeclaredLengthExceeded

Offered bytes exceed the declared wire length.

DeclaredLengthMismatch

End-of-stream actual bytes differ from the declared length.

UnexpectedEventEnd

Caller-cancelled event streams cannot end as finite streams.

ZeroProgressLimitExceeded

Consecutive observations made no progress beyond policy tolerance.

ArithmeticOverflow

Counter arithmetic or platform length conversion overflowed.

Trait Implementations

impl Eq for StreamProgressError

impl Error for StreamProgressError

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 PartialEq for StreamProgressError

fn eq(&self, other: &StreamProgressError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
