Struct specs::common::Merge

pub struct Merge<F> { /* private fields */ }

A system which merges Ready futures into the persistent storage. Please note that your World has to contain a component storage for F and F::Item.

In case of an error, it will be added to the Errors resource.

Implementations

impl<F> Merge<F>

pub fn new() -> Self

Creates a new merge system.

Trait Implementations

impl<F> Default for Merge<F>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T, F> System<'a> for Merge<F>where
    T: Component + Send + Sync + 'static,
    F: Future<Item = T, Error = BoxedErr> + Component + Send + Sync,

type SystemData = (Read<'a, EntitiesRes, DefaultProvider>, Read<'a, Errors, DefaultProvider>, Storage<'a, F, FetchMut<'a, MaskedStorage<F>>>, Storage<'a, T, FetchMut<'a, MaskedStorage<T>>>)

The resource bundle required to execute this system.

fn run(&mut self, (entities, errors, futures, pers): Self::SystemData)

Executes the system with the required system data.

fn running_time(&self) -> RunningTime

Returns a hint how long the system needs for running. This is used to optimize the way they’re executed (might allow more parallelization).

fn accessor<'b>(&'b self) -> AccessorCow<'a, 'b, Self>

Return the accessor from the SystemData.

fn setup(&mut self, res: &mut Resources)

Sets up the Resources using Self::SystemData::setup.

fn dispose(self, res: &mut Resources)where
    Self: Sized,

Performs clean up that requires resources from the Resources.
