Struct Failure

pub struct Failure(pub String);

It is recommend to use failure! or failure_raw! to construct a Failure as this saves typing "...".to_owned() or format!("...").

See module level documentation for more docs

Implementations

impl Failure

pub fn boxed(self) -> Box<dyn Error>

Transforms the Failure into a Box<dyn Error>

pub fn err_boxed<T, E: From<Box<dyn Error>>>(self) -> Result<T, E>

Transforms the Failure into a Result::Err(E) when E implements From<Box<dyn Error>>

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

Transforms the Failure into a Result::Err(Failure)

Trait Implementations

impl Debug for Failure

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

Formats the value using the given formatter.

impl Display for Failure

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

Formats the value using the given formatter.

impl Error for Failure

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.
