Struct Error 

pub struct Error<T: ?Sized, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized = NoContext> { /* private fields */ }

Represents errors that occur when the value of type T does not satisfy the predicate P.

The context C provides additional information about the error, and defaults to NoContext.

For instance, False expects nothing and its code is false, so the error message is:

expected nothing (no context) [false]

Implementations

impl<T: ?Sized, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized> Error<T, P, C>

pub const fn get_ref(&self) -> &T

Returns the contained value reference.

impl<T, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized> Error<T, P, C>

pub fn get(self) -> T

Returns the contained value.

Trait Implementations

impl<T: ?Sized, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized> Debug for Error<T, P, C>

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

Formats the value using the given formatter.

impl<T: ?Sized, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized> Display for Error<T, P, C>

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

Formats the value using the given formatter.

impl<T: ?Sized, P: Predicate<T> + ?Sized, C: TypeStr + ?Sized> Error for Error<T, P, C>

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>)
