Zero/One Trait
Deprecated because letting the generic type to implement either From<u8>
or From<i8>
is enough.
pub trait ZeroOne: Sized + Copy {
fn zero() -> Self;
fn one() -> Self;
}
macro_rules! impl_zero_one {
($($ty:ty) *) => { $(
impl ZeroOne for $ty {
#[inline(always)]
fn one() -> Self {1}
#[inline(always)]
fn zero() -> Self {0}
}
)+ };
}
impl_zero_one!(isize i8 i16 i32 i64 i128 usize u8 u16 u32 u64 u128);
