Enum ZwinderError 

#[non_exhaustive]
pub enum ZwinderError {
    Decompress(String),
    LengthMismatch {
        kf: usize,
        dl: usize,
    },
    MissingKeyframe(u64),
}

Errors raised when a stored Zwinder frame 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.

Decompress(String)

LZ4 decompression of a stored body failed (corrupt entry).

LengthMismatch

A delta entry’s keyframe is missing or its length disagrees with the delta (shouldn’t happen for a stable build — snapshot shape is fixed).

Fields

kf: usize

Keyframe length.

dl: usize

Delta length.

MissingKeyframe(u64)

A delta referenced a keyframe that isn’t present in the store. By construction every delta is stored after a keyframe at-or-before its frame; this indicates a corrupt store.

Trait Implementations

impl Debug for ZwinderError

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

Formats the value using the given formatter.

impl Display for ZwinderError

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

Formats the value using the given formatter.

impl Error for ZwinderError

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.
