Enum CacheError 

pub enum CacheError {
    Io(Error),
    Wire(SparseWireError),
    FilterMismatch,
}

Errors raised by the cache I/O helpers. Wrapping the io::Error directly keeps the call sites concise — the cache is best-effort, so callers usually log-and-continue rather than blow up.

Variants

Io(Error)

Wire(SparseWireError)

FilterMismatch

Cache file existed but recorded a different filter hash. Not strictly an “error” — callers usually treat this as a cache miss and re-fetch — but distinct from the I/O / wire variants so a misfit cache doesn’t get silently overwritten.

Trait Implementations

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Error for CacheError

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 CacheError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<SparseWireError> for CacheError

fn from(source: SparseWireError) -> Self

Converts to this type from the input type.
