Enum SnapshotError 

pub enum SnapshotError {
    Io(Error),
    InvalidFormat(String),
    Corrupted,
    Backend(String),
}

Errors from snapshot operations.

Uses thiserror to match crate::KvError; unlike KvError (which is Clone and so flattens its causes to strings), snapshot errors are observed by a single caller, so Io keeps its #[source] chain via #[from].

Variants

Io(Error)

InvalidFormat(String)

Corrupted

Backend(String)

A pluggable SnapshotStore backend (e.g. the fjall on-disk store) reported an error. Kept backend-agnostic — no backend type leaks into this enum’s signature — so enabling a backend feature does not change the public error surface.

Trait Implementations

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl Display for SnapshotError

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

Formats the value using the given formatter.

impl Error for SnapshotError

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<Error> for SnapshotError

fn from(source: Error) -> Self

Converts to this type from the input type.
