Fatal error

Implementations

impl<E> FatalError<E>

pub fn is_error(&self) -> bool

return true if this error non is fatal

pub fn is_fatal(&self) -> bool

return true if this error is fatal

pub fn into_inner(self) -> E

transforms the error into it’s inner type

pub fn map<E2, F>(self, f: F) -> FatalError<E2>

where F: FnOnce(E) -> E2,

applies f to the inner error preserving the FatalError::Error or FatalError::Fatal state

pub fn escalate(self) -> Self

Makes this error fatal

pub fn deescalate(self) -> Self

Makes this error non fatal

pub fn fatality(self) -> Result<E, Self>

Return Ok(E) if the error is non fatal else Err(Self) is returned

pub fn recover(self) -> Result<E, E>

return Err(E) if the error is fatal otherwise Ok(E) is returned

pub fn map_error<T, F>(self, f: F) -> Result<T, Self>

where F: FnOnce(E) -> Result<T, Self>,

recover a non fatal error with the given closure

pub fn map_fatal<T, F>(self, f: F) -> Result<T, Self>

where F: FnOnce(E) -> Result<T, Self>,

recover from a fatal error with the given closure

pub fn then<T, F>(self, f: F) -> Result<T, Self>

where F: FnOnce(E) -> Result<T, Self>,

recover from either an error or a fatal error with the given closure

Trait Implementations

impl<E: Clone> Clone for FatalError<E>

fn clone(&self) -> FatalError<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for FatalError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for FatalError<E>

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

Formats the value using the given formatter.

impl<E: StdError + 'static> Error for FatalError<E>

fn source(&self) -> Option<&(dyn StdError + '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<E: PartialEq> PartialEq for FatalError<E>

fn eq(&self, other: &FatalError<E>) -> 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.
