Enum OpenStreamError 

pub enum OpenStreamError {
    Abort {
        token: String,
        reason: Option<String>,
    },
    Policy(String),
    Sequence(String),
}

Errors raised while reading, writing, or sequencing an open stream.

Variants

Abort

The stream was aborted locally or by the remote peer (terminal).

Fields

token: String

The progressToken of the aborted stream.

reason: Option<String>

Optional advisory reason supplied in the abort frame.

Policy(String)

A stream violated local admission or buffering policy (concurrency, buffered-chunk count, buffered+queued byte budget).

Sequence(String)

Frames violated CEP-41 lifecycle or ordering rules (non-increasing progress, stale/duplicate chunkIndex, frame before start, frame after a terminal close/abort, incomplete close.lastChunkIndex).

Implementations

impl OpenStreamError

pub fn abort(token: impl Into<String>, reason: Option<String>) -> Self

Construct an OpenStreamError::Abort.

pub fn is_abort(&self) -> bool

Returns true if this is a terminal abort.

Trait Implementations

impl Clone for OpenStreamError

fn clone(&self) -> OpenStreamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenStreamError

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

Formats the value using the given formatter.

impl Display for OpenStreamError

impl Eq for OpenStreamError

impl Error for OpenStreamError

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<OpenStreamError> for Error

fn from(source: OpenStreamError) -> Self

Converts to this type from the input type.

impl PartialEq for OpenStreamError

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

Equality operator ==.

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

Inequality operator !=.
