Trait ToI8 

pub trait ToI8: CastInto<Self::Output> {
    type Output;

    // Required methods
    fn to_i8(self) -> Self::Output;
    fn to_i8_range(self) -> Self::Output;
}

Helper trait based on CastInto and CastRangeInto Also work on composite like std::array, Vector…

Required Associated Types

type Output

Required Methods

fn to_i8(self) -> Self::Output

Same semantics as the as keyword: 4f32 as u64, and the From trait, but generic friendly.

Like the as keyword, the result might lose some precision.

fn to_i8_range(self) -> Self::Output

Remap the value RangeDefault to the RangeDefault of the target type, in a generic friendly way, and similar to the From trait.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
