Trait ToZero 

pub trait ToZero<T>:
    Sized
    + PartialEq
    + Copy {
    // Required method
    fn to_zero() -> T;
}

Available on crate feature to_zero only.

Trait for implementing the null value of types.

assert_eq!(u8::to_zero(), u8::MIN);
assert_eq!(i16::to_zero(), 0_i16);
assert_eq!(u32::to_zero(), u32::MIN);
assert_eq!(i64::to_zero(), 0_i64);
assert_eq!(usize::to_zero(), usize::MIN);
assert_eq!(i128::to_zero(), 0_i128);

Required Methods

fn to_zero() -> T

Returns zero of types.

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.
