Implementations

impl CacheError

pub fn kind(&self) -> &'static str

Returns the error kind as a string

pub fn message(&self) -> String

Returns the error message without the error kind prefix

pub fn new<S: Into<String>>(message: S) -> Self

Creates a new generic error

pub fn is_io_error(&self) -> bool

Checks if the error is an I/O error

pub fn is_not_found(&self) -> bool

Checks if the error indicates something wasn’t found

pub fn is_permission_denied(&self) -> bool

Checks if the error indicates permission was denied

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, f: &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(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CacheError

fn from(err: Error) -> Self

Converts to this type from the input type.
