Expand description

The different things we could suggest.

Variants§

§

Outlives(RegionName, SmallVec<[RegionName; 2]>)

Outlives(a, [b, c, d, …]) => ’a: ’b + ’c + ’d + …

§

Equal(RegionName, RegionName)

’a = ’b

§

Static(RegionName)

’a: ’static i.e. ’a = ’static and the user should just use ’static

§

type Error = Infallible

The type returned in the event of a conversion error.
source§

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.
source§

impl<T, U> TryInto<U> for Twhere U: TryFrom<T>,

§

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
