Implementations

impl<T, U, D> Error<T, U, D>

where T: Error + Send + 'static, U: Error + Send + 'static, D: Digest,

pub fn resolver(err: impl Into<U>) -> Self

pub fn database(err: impl Into<T>) -> Self

Trait Implementations

impl<T, U, D> Debug for Error<T, U, D>

where T: Error + Send + 'static + Debug, U: Error + Send + 'static + Debug, D: Digest + Debug,

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

Formats the value using the given formatter.

impl<T, U, D> Display for Error<T, U, D>

where T: Error + Send + 'static + Display, U: Error + Send + 'static + Debug, D: Digest + Debug, Target<D>: Debug,

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

Formats the value using the given formatter.

impl<T, U, D> Error for Error<T, U, D>

where T: Error + Send + 'static, U: Error + Send + 'static, D: Digest, Self: Debug + Display,

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.
