Expand description

Trait representing how the node data will be stored in a self referential collection.

Required Methods§

source

fn active(value: T) -> Self

Creates a new active node data with the given value.

source

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

Returns a reference to the stored value; returns None if the node is not active.

source

fn get_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to the stored value; returns None if the node is not active.

source

fn swap_data(&mut self, new_value: T) -> T

Updates the node data with the new_value and returns back the old value.
