Struct const_panic::fmt::IsPanicFmt

source · [−]

pub struct IsPanicFmt<S: ?Sized, T: ?Sized, K> { /* private fields */ }

Expand description

A marker type that proves that S implements PanicFmt<This = T, Kind = K>.

Used by const_panic macros to coerce both standard library and user-defined types into some type that has a to_panicvals method.

Implementations

source

impl<T: PanicFmt + ?Sized> IsPanicFmt<T, T::This, T::Kind>

source

pub const NEW: Self

Constucts an IsPanicFmt

source

impl<S: ?Sized, T: ?Sized, K> IsPanicFmt<S, T, K>

source

pub const fn infer(self, _: &S) -> Self

Infers the S type parameter with the argument.

Because the only ways to construct IsPanicFmt use IsPanicFmt<S, S::This, S::Kind>, the other type parameters are inferred along with S.

source

impl<S: ?Sized, T: ?Sized> IsPanicFmt<S, T, IsStdType>

source

pub const fn coerce(self, x: &T) -> StdWrapper<&T>

For coercing &T to StdWrapper<&T>.

source

impl<S: ?Sized, T: ?Sized> IsPanicFmt<S, T, IsCustomType>

source

pub const fn coerce(self, x: &T) -> &T

For coercing &T (with any amount of stacked references) to &T.
