pub struct DynParamBuilder<'a>(/* private fields */);Expand description
A SystemParamBuilder for a DynSystemParam.
See the DynSystemParam docs for examples.
Implementations§
Source§impl<'a> DynParamBuilder<'a>
impl<'a> DynParamBuilder<'a>
Sourcepub fn new<T: SystemParam + 'static>(
builder: impl SystemParamBuilder<T> + 'a,
) -> Self
pub fn new<T: SystemParam + 'static>( builder: impl SystemParamBuilder<T> + 'a, ) -> Self
Creates a new DynParamBuilder by wrapping a SystemParamBuilder of any type.
The built DynSystemParam can be downcast to T.

self,
world: &mut World,
) -> <DynSystemParam<'w, 's> as SystemParam>::State
fn build( self, world: &mut World, ) -> <DynSystemParam<'w, 's> as SystemParam>::State
Registers any
World access used by this SystemParam
and creates a new instance of this param’s State.Source§fn build_state(self, world: &mut World) -> SystemState<P>
fn build_state(self, world: &mut World) -> SystemState<P>
Create a
SystemState from a SystemParamBuilder.
To create a system, call SystemState::build_system on the result.Auto Trait Implementations§
