Trait MapExpect 

pub trait MapExpect<'a, T> {
    // Required method
    fn map_expect(self, msg: &'a str) -> T;
}

Required Methods

fn map_expect(self, msg: &'a str) -> T

Calls expect(msg) on the mapped Result value. This is similar to map(Result::unwrap) but composes an expect call and message without requiring a closure.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
