Enum ReadError 

pub enum ReadError<E> {
    Range(RangeError),
    Source(E),
    ShortRead {
        range: Range<usize>,
        expected: usize,
        actual: usize,
    },
}

A read-through failure.

Variants

Range(RangeError)

Invalid range or cache payload.

Source(E)

Source-specific failure.

ShortRead

The source returned fewer or more bytes than requested.

Fields

range: Range<usize>

Requested byte range.

expected: usize

Required byte length.

actual: usize

Actual byte length.

Trait Implementations

impl<E: Debug> Debug for ReadError<E>

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

Formats the value using the given formatter.

impl<E> Display for ReadError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for ReadError<E>

where E: Error + 'static, Self: Debug + Display,

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<E> From<RangeError> for ReadError<E>

fn from(source: RangeError) -> Self

Converts to this type from the input type.
