Trait Widen 

pub trait Widen: Integer {
    // Required method
    fn widen<T>(self) -> T
       where Self: WidenTarget<T>;
}

Widen to an integer of the same size or larger, preserving its value.

assert_eq!(0_u8.widen::<u16>(), 0_u16);
assert_eq!(0_u16.widen::<u32>(), 0_u32);
assert_eq!(0_u32.widen::<u64>(), 0_u64);
assert_eq!(0_u64.widen::<u128>(), 0_u128);

assert_eq!((-1_i8).widen::<i16>(), -1_i16);
assert_eq!((-1_i16).widen::<i32>(), -1_i32);
assert_eq!((-1_i32).widen::<i64>(), -1_i64);
assert_eq!((-1_i64).widen::<i128>(), -1_i128);

Required Methods

fn widen<T>(self) -> T

where Self: WidenTarget<T>,

Widen an integer to an integer of the same size or larger, preserving its value.

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.
