Enum MruPersistError 

pub enum MruPersistError {
    Io(Error),
    Encode(EncodeError),
    Decode(DecodeError),
    VersionMismatch {
        expected: u32,
        found: u32,
    },
}

Errors from MRU index persistence. The host (slice 14c) decides whether to discard + start fresh, retry, or surface to the user. Default policy: discard on VersionMismatch / Decode; log + retry on Io (write); never block boot.

Variants

impl Error for MruPersistError

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.
