Trait shred::TaskData

pub trait TaskData<'a> {
    fn fetch(res: &'a Resources) -> Self;
    unsafe fn reads() -> Vec<ResourceId>;
    unsafe fn writes() -> Vec<ResourceId>;
}

A struct implementing task data indicates that it bundles some resources which are required for the execution.

Required Methods

fn fetch(res: &'a Resources) -> Self

Creates a new resource bundle by fetching the required resources from the Resources struct.

Contract

Only fetch the resources you returned from reads / writes!

unsafe fn reads() -> Vec<ResourceId>

A list of [ResourceId]s the bundle needs read access to in order to build the target resource bundle.

Contract

Exactly return the dependencies you're going to fetch! Doing otherwise will cause a data race.

This method is only executed once, thus the returned value may never change (otherwise it has no effect).

unsafe fn writes() -> Vec<ResourceId>

A list of [ResourceId]s the bundle needs write access to in order to build the target resource bundle.

Contract

Exactly return the dependencies you're going to fetch! Doing otherwise will cause a data race.

This method is only executed once, thus the returned value may never change (otherwise it has no effect).
