Trait Cursor 

pub(crate) trait Cursor<'a, T>: Send {
    // Required methods
    fn state(&self) -> &State<'a>;
    fn state_mut(&mut self) -> &mut State<'a>;
    fn count(&self) -> (usize, Option<usize>);
    fn fetch(&self) -> Option<T>;
    fn seek(&mut self);

    // Provided methods
    fn get(&self) -> Option<Result<T>> { ... }
    fn seek_and_get(&mut self) -> Option<Result<T>> { ... }
}

Required Methods

fn state(&self) -> &State<'a>

fn state_mut(&mut self) -> &mut State<'a>

fn count(&self) -> (usize, Option<usize>)

fn fetch(&self) -> Option<T>

fn seek(&mut self)

Provided Methods

fn get(&self) -> Option<Result<T>>

fn seek_and_get(&mut self) -> Option<Result<T>>

Dyn Compatibility

This trait is dyn compatible.

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