Implementations

impl FxfsError

pub fn matches(&self, error: &Error) -> bool

A helper to match against this FxfsError against the root cause of an anyhow::Error.

The main application of this helper is to allow us to match an anyhow::Error against a specific case of FxfsError in a boolean expression, such as:

let result: Result<(), anyhow:Error> = foo(); match result { Ok(foo) => Ok(foo), Err(e) if &FxfsError::NotFound.matches(e) => { … } Err(e) => Err(e) }

Trait Implementations

impl Clone for FxfsError

fn clone(&self) -> FxfsError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FxfsError

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

Formats the value using the given formatter.

impl Display for FxfsError

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

Formats the value using the given formatter.

impl Error for FxfsError

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<FxfsError> for Status

fn from(err: FxfsError) -> Status

Converts to this type from the input type.

impl PartialEq for FxfsError

fn eq(&self, other: &FxfsError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
