Trait Implementations

impl<'a, T: Debug + LinkType> Debug for Error<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> Display for Error<'a, T>

where T: Display + LinkType, Cow<'a, T>: Display,

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

Formats the value using the given formatter.

impl<'a, T: LinkType> Error for Error<'a, T>

where 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.

impl<'a, T: LinkType> From<Box<dyn Error + Sync + Send>> for Error<'a, T>

fn from(source: Box<dyn Error + Sync + Send>) -> Self

Converts to this type from the input type.

impl<'a, T: LinkType> From<Error> for Error<'a, T>

fn from(source: Error) -> Self

Converts to this type from the input type.
