Enum PumpFailure 

#[non_exhaustive]
pub enum PumpFailure<E> {
    Step(E),
    Io(Error),
    NeedsRandomAccess(InputRequest),
    WindowLimit {
        needed: usize,
        limit: usize,
    },
    Protocol(ProtocolViolation),
    Input(InputError),
}

Failure of a drive over a sequential std::io::Read stream.

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.

Step(E)

The stage failed.

Io(Error)

Reading the stream failed.

NeedsRandomAccess(InputRequest)

The stage asked for bytes behind the stream position, or for the total length before the stream ended. A stream cannot serve either; wrap it in BufferedReadAt and use a ReadAtCursor.

WindowLimit

The stage needs more contiguous bytes than max_window allows.

Fields

needed: usize

Bytes the stage asked for in one input.

limit: usize

The configured limit.

Protocol(ProtocolViolation)

The stage broke the protocol.

Input(InputError)

Fallible input allocation or address admission failed.

Trait Implementations

impl<E: Debug> Debug for PumpFailure<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for PumpFailure<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for PumpFailure<E>

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>)
