Trait ListSelectors

pub trait ListSelectors<T> {
    // Required methods
    fn first_that<F>(&self, predicate: F) -> Option<(&T, usize)>
       where F: Fn(&T) -> bool;
    fn last_that<F>(&self, predicate: F) -> Option<(&T, usize)>
       where F: Fn(&T) -> bool;
}

Required Methods

fn first_that<F>(&self, predicate: F) -> Option<(&T, usize)>

where F: Fn(&T) -> bool,

fn last_that<F>(&self, predicate: F) -> Option<(&T, usize)>

where F: Fn(&T) -> bool,

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.
