Trait Collection 

pub trait Collection<T: ?Sized> {
    // Required methods
    fn len(&self) -> usize;
    fn get(&self, idx: usize) -> Option<&T>;
    fn get_mut(&mut self, idx: usize) -> Option<&mut T>;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Required Methods

fn len(&self) -> usize

fn get(&self, idx: usize) -> Option<&T>

fn get_mut(&mut self, idx: usize) -> Option<&mut T>

Provided Methods

fn is_empty(&self) -> bool

Trait Implementations

impl<T: ?Sized> Collection<T> for &mut dyn Collection<T>

fn len(&self) -> usize

fn get(&self, idx: usize) -> Option<&T>

fn get_mut(&mut self, idx: usize) -> Option<&mut T>

fn is_empty(&self) -> bool

Dyn Compatibility

This trait is dyn compatible.

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