Enum CacheError 

pub enum CacheError {
    Io(Error),
    IoWithContext {
        operation: &'static str,
        path: PathBuf,
        source: Error,
    },
    Serialization(Error),
    Backend(BackendError),
}

Error types for cache operations (legacy, for backward compatibility)

Variants

Io(Error)

IO error during cache operations (generic)

IoWithContext

IO error with path context for better diagnostics

Fields

operation: &'static str

path: PathBuf

source: Error

Serialization(Error)

JSON serialization error

Backend(BackendError)

Backend error

Implementations

impl CacheError

pub fn io_with_context( operation: &'static str, path: impl Into<PathBuf>, source: Error, ) -> Self

Create an IO error with path context

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.
