Struct actions::Chain

pub struct Chain<Action> where
    Action: Merge,  { /* fields omitted */ }

A chain of actions.

Can be used to store 'macros'.

Methods

impl<Action: Merge> Chain<Action>

pub fn new() -> Self

Create a new chain of actions.

pub fn compress(&mut self)

Merges as much actions in the chain as possible.

For example, if the chain contains an action that cancels out the previous action, both of the actions can be removed from the chain.

pub fn push(&mut self, action: Action)

Push an action to the chain.

pub fn len(&self) -> usize

The amount of action currently in the chain.

pub fn actions(&self) -> &Vec<Action>

The actions in the chain.
