Enum RewindError 

#[non_exhaustive]
pub enum RewindError {
    MissingKeyframe,
    Decompress(String),
    LengthMismatch {
        kf: usize,
        dl: usize,
    },
}

Errors raised by RewindRing::pop_back when an entry can’t be reconstructed.

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.

MissingKeyframe

The keyframe needed to delta-apply this entry was already evicted.

Decompress(String)

LZ4 decompression failed (corrupt entry).

LengthMismatch

Snapshot lengths after delta-application don’t match.

Fields

kf: usize

Keyframe length.

dl: usize

Delta length.

Trait Implementations

impl Debug for RewindError

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

Formats the value using the given formatter.

impl Display for RewindError

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

Formats the value using the given formatter.

impl Error for RewindError

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.
