Trait az::SaturatingCastFrom

pub trait SaturatingCastFrom<Src> {
    fn saturating_cast_from(src: Src) -> Self;
}

Used to cast, saturating if the value does not fit.

This trait enables trait constraints for casting in the opposite direction to SaturatingCast.

Examples

use az::SaturatingCastFrom;
trait Tr {
    type Assoc: SaturatingCastFrom<u8>;
    fn saturating_assoc_from_u8(a: u8) -> Self::Assoc {
        SaturatingCastFrom::saturating_cast_from(a)
    }
}
impl Tr for () {
    type Assoc = i8;
}
assert_eq!(<() as Tr>::saturating_assoc_from_u8(5u8), 5i8);
assert_eq!(<() as Tr>::saturating_assoc_from_u8(255u8), 127i8);

Required Methods

fn saturating_cast_from(src: Src) -> Self

Casts the value.
