Implementations

impl Error

pub fn other<E>(error: E) -> Self

where E: StdError + Send + Sync + 'static,

Creates an Error from any other underlying reason.

pub fn message<T: Display>(message: T) -> Self

Creates an Error from a message.

pub fn unknown_param(name: &'static str) -> Self

Creates an UnknownParam error from a statically-known parameter name.

pub fn unknown_param_dyn<T: Display>(message: T) -> Self

Creates an UnknownParam error from a dynamic parameter name.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
