Struct Cursor

pub struct Cursor<'node, T: 'node> { /* private fields */ }

A Cursor is an iterator over a node and it’s tail. It is an active item, which owns the next node it would return.

Due to the design of rust’s Iterator trait, Cursor cannot implement Iterator.

Implementations

impl<'node, T: 'node> Cursor<'node, T>

pub fn next<'tail>(&'tail mut self) -> Option<TailValRef<'node, 'tail, T>>

(Optionally) returns the next element of this cursor.

This cursor is unusable as long as the 'tail lifetime is still referenced.

Trait Implementations

impl<'node, T: 'node> Drop for Cursor<'node, T>

fn drop(&mut self)

Executes the destructor for this type.
