Enum ReadError 

#[non_exhaustive]
pub enum ReadError {
    Request(RequestError),
    ReadUnwritten(StreamPosition),
}

Errors returned by unary read operations.

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.

Request(RequestError)

A network request error.

ReadUnwritten(StreamPosition)

The requested position has not been written.

Implementations

impl ReadError

pub fn is_retryable(&self) -> bool

Whether retrying the operation is safe or sensible.

pub fn request_error(&self) -> Option<&RequestError>

Return the underlying request error, if present.

Trait Implementations

impl Clone for ReadError

fn clone(&self) -> ReadError

Returns a duplicate 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<ReadError> for ReadSessionError

fn from(source: ReadError) -> Self

Converts to this type from the input type.

impl From<RequestError> for ReadError

fn from(source: RequestError) -> Self

Converts to this type from the input type.
