pub trait CastRangeFrom<T> {
// Required method
fn cast_range_from(value: T) -> Self;
}Expand description
Remap the value RangeDefault to the RangeDefault of the target type,
in a generic friendly way, and similar to the From trait.
[Self::RANGE_MIN..Self::RANGE_MAX] => [T::RANGE_MIN..T::RANGE_MAX]
One should always prefer implementing CastRangeFrom over CastRangeInto because implementing CastRangeFrom automatically provides one with an implementation of CastRangeInto thanks to the blanket implementation in the hexga_number library.
use hexga_number::prelude::*;
assert_eq!(u8::cast_range_from(1f32), 255u8);
assert_eq!(u8::cast_range_from(0f32), 0u8);
let casted_range : u16 = u8::MAX.cast_range_into();
assert_eq!(casted_range, u16::MAX);Also work with composite like std::array, [Vector]…

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
