Trait argmin::prelude::AsPrimitive

pub trait AsPrimitive<T>: 'static + Copy where
    T: 'static + Copy, {
    fn as_(self) -> T;
}

A generic interface for casting between machine scalars with the as operator, which admits narrowing and precision loss. Implementers of this trait AsPrimitive should behave like a primitive numeric type (e.g. a newtype around another primitive), and the intended conversion must never fail.

Examples

let three: i32 = (3.14159265f32).as_();
assert_eq!(three, 3);

Safety

Currently, some uses of the as operator are not entirely safe. In particular, it is undefined behavior if:

• A truncated floating point value cannot fit in the target integer type (#10184);

let x: u8 = (1.04E+17).as_(); // UB

• Or a floating point value does not fit in another floating point type (#15536).

let x: f32 = (1e300f64).as_(); // UB

Required methods

fn as_(self) -> T

Convert a value to another, using the as operator.
