Errors that a stream can encounter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

#[non_exhaustive]

InvalidStream

The Stream ID which was referenced is invalid

This could mean the ID is no longer tracked by the Connection.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

StreamReset

The Stream had been reset by the peer via a RESET_STREAM frame.

Inside this frame the peer will deliver an error code, which will be provided by the parameter.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

error: Error

source: &'static Location<'static>

#[non_exhaustive]

SendAfterFinish

A send attempt had been performed on a Stream after it was closed

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

MaxStreamDataSizeExceeded

Attempting to write data would exceed the stream limit

This is caused because the maximum possible amount of data (2^62-1 bytes) had already been written to the Stream.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

ConnectionError

The Stream was reset due to a Connection Error

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

error: Error

#[non_exhaustive]

NonReadable

The stream is not readable

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

NonWritable

The stream is not writable

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

SendingBlocked

The stream is blocked on writing data

This is caused by trying to send data before polling readiness

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

source: &'static Location<'static>

#[non_exhaustive]

NonEmptyOutput

The stream was provided a non-empty placeholder buffer for receiving data.

The application should ensure only empty buffers are provided to receive calls, otherwise it can lead to data loss on the stream.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

Implementations

impl StreamError

pub fn source(&self) -> &'static Location<'static>

Returns the panic::Location for the error

Trait Implementations

impl Clone for StreamError

fn clone(&self) -> StreamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamError

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

Formats the value using the given formatter.

impl Display for StreamError

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

Formats the value using the given formatter.

impl Error for StreamError

Available on crate feature std only.

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<ConnectionClose<'_>> for StreamError

fn from(error: ConnectionClose<'_>) -> Self

Converts to this type from the input type.

impl From<Error> for StreamError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StreamError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<StreamError> for Error

Available on crate feature std only.

fn from(error: StreamError) -> Self

Converts to this type from the input type.

impl From<StreamError> for ErrorKind

Available on crate feature std only.

fn from(error: StreamError) -> Self

Converts to this type from the input type.

impl PartialEq for StreamError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryInto for StreamError

fn application_error(&self) -> Option<Error>

Returns the associated Error, if any

impl Copy for StreamError

impl Eq for StreamError

impl StructuralPartialEq for StreamError
