Enum ReadError

pub enum ReadError {
    Reset(VarInt),
    ConnectionLost(ConnectionError),
    ClosedStream,
    IllegalOrderedRead,
    ZeroRttRejected,
    BufferTooShort,
}

Errors that arise from reading from a stream.

Variants

Reset(VarInt)

The peer abandoned transmitting data on this stream.

Carries an application-defined error code.

ConnectionLost(ConnectionError)

The connection was lost.

ClosedStream

The stream has already been stopped, finished, or reset.

IllegalOrderedRead

Attempted an ordered read following an unordered read.

Performing an unordered read allows discontinuities to arise in the receive buffer of a stream which cannot be recovered, making further ordered reads impossible.

ZeroRttRejected

This was a 0-RTT stream and the server rejected it.

Can only occur on clients for 0-RTT streams, which can be opened using Connecting::into_0rtt().

BufferTooShort

The stream is larger than the user-supplied buffer capacity.

Can only occur when using read_to_end().

Trait Implementations

impl Clone for ReadError

fn clone(&self) -> ReadError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadError

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

Formats the value using the given formatter.

impl Display for ReadError

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

Formats the value using the given formatter.

impl Error for ReadError

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<ConnectionError> for ReadError

fn from(source: ConnectionError) -> Self

Converts to this type from the input type.

impl From<ReadError> for Error

fn from(x: ReadError) -> Self

Converts to this type from the input type.

impl From<ReadError> for ReadExactError

fn from(source: ReadError) -> Self

Converts to this type from the input type.

impl From<ReadError> for StreamErrorIncoming

Available on crate feature h3 only.

fn from(e: ReadError) -> Self

Converts to this type from the input type.

impl From<ReadableError> for ReadError

fn from(e: ReadableError) -> Self

Converts to this type from the input type.

impl From<StoppedError> for ReadError

fn from(e: StoppedError) -> Self

Converts to this type from the input type.

impl PartialEq for ReadError

fn eq(&self, other: &ReadError) -> 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.
