Struct CommandQueue

Source
pub struct CommandQueue { /* private fields */ }
Expand description

Densely and efficiently stores a queue of heterogenous types implementing Command.

Implementations§

Source§

impl CommandQueue

Source

pub fn push<C>(&mut self, command: C)
where C: Command,

Push a Command onto the queue.

Source

pub fn apply(&mut self, world: &mut World)

Execute the queued Commands in the world after applying any commands in the world’s internal queue. This clears the queue.

Source

pub fn append(&mut self, other: &mut CommandQueue)

Take all commands from other and append them to self, leaving other empty

Source

pub fn is_empty(&self) -> bool

Returns false if there are any commands in the queue
