Trait valence::ecs::system::BuildableSystemParam

pub trait BuildableSystemParam: SystemParam {
    type Builder<'b>;

    // Required method
    fn build(
        world: &mut World,
        meta: &mut SystemMeta,
        func: impl FnOnce(&mut Self::Builder<'_>),
    ) -> Self::State;
}

A parameter that can be built with SystemBuilder

Required Associated Types

type Builder<'b>

A mutable reference to this type will be passed to the builder function

Required Methods

fn build( world: &mut World, meta: &mut SystemMeta, func: impl FnOnce(&mut Self::Builder<'_>), ) -> Self::State

Constructs SystemParam::State for Self using a given builder function
