Enum Error

pub enum Error {
    Memory(Error),
    Storage(Error),
    Other(Box<dyn Error + Send + Sync + 'static>),
}

Errors enum for foyer.

Variants

Memory(Error)

foyer in-memory cache error.

Storage(Error)

foyer disk cache error.

Other(Box<dyn Error + Send + Sync + 'static>)

Other error.

Implementations

impl Error

pub fn other<E>(e: E) -> Self

where E: Into<Box<dyn Error + Send + Sync + 'static>>,

Create customized error.

pub fn downcast<T>(self) -> Result<T, Self>

where T: Error + 'static,

Downcast error to a specific type.

Only Other variant can be downcasted. If the error is not Other, it will return an error indicating that downcasting is not possible.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error
