Trait ConstCheckedSub 

pub trait ConstCheckedSub: Sized + ConstOverflowingSub {
    // Required method
    fn checked_sub(&self, v: &Self) -> Option<Self>;
}

Const-compatible checked subtraction.

Required Methods

fn checked_sub(&self, v: &Self) -> Option<Self>

Checked subtraction. Returns None if overflow occurred.

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.
