Expand description

Trait for layered type merging.

Required Methods§

Merge the values, prioritizing self.

let a = Some("a");
let b = Some("b");

assert_eq!(a.over(b), Some("a"));

Merge the values, prioritizing other.

let a = Some("a");
let b = Some("b");

assert_eq!(a.under(b), Some("b"));

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
