Trait Compare

pub trait Compare<T, U = T> {
    // Required method
    fn cmp(lhs: &T, rhs: &U) -> Ordering;
}

Ordering logic provided to Zip via Strategy.

Examples

struct IndexCompare;

impl<T, U> Compare<(usize, T), (usize, U)> for IndexCompare {
    fn cmp(lhs: &(usize, T), rhs: &(usize, U)) -> Ordering {
        (lhs.0).cmp(&(rhs.0))
    }
}

Required Methods

fn cmp(lhs: &T, rhs: &U) -> Ordering

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.
