Struct sauron_core::dom::cmd::Cmd

pub struct Cmd<DSP>(pub Vec<Rc<dyn Fn(DSP)>>);

Cmd is a command to be executed by the system. This is returned at the init function of a component and is executed right after instantiation of that component. Cmd required a DSP object which is the Program as an argument The emit function is called with the program argument. The callback is supplied with the program an is then executed/emitted.

Implementations

impl<DSP> Cmd<DSP> where
    DSP: Clone + 'static, 

pub fn new<F>(f: F) -> Self where
    F: Fn(DSP) + 'static, 

creates a new Cmd from a function

pub fn batch(cmds: Vec<Self>) -> Self

creates a unified Cmd which batches all the other Cmds in one.

pub fn none() -> Self

A Cmd with no callback, similar to NoOp.

pub fn emit(self, program: &DSP)

Executes the Cmd
