Struct shred::Par

pub struct Par<H, T> { /* fields omitted */ }

Runs two tasks in parallel. These two tasks are called head and tail in the following documentation.

Methods

impl<H> Par<H, Nil>

pub fn new(head: H) -> Self

Creates a new Par struct, with the tail being a no-op.

pub fn with<T>(self, sys: T) -> Par<Par<H, T>, Nil> where
    H: for<'a> RunWithPool<'a>,
    T: for<'a> RunWithPool<'a>, 

Adds sys as the second job and returns a new Par struct with the previous struct as head and a no-op tail.

Trait Implementations

impl<'a, H, T> RunWithPool<'a> for Par<H, T> where
    H: RunWithPool<'a> + Send,
    T: RunWithPool<'a> + Send, 

fn setup(&mut self, world: &mut World)

Sets up World for a later call to run.

fn run(&mut self, world: &'a World, pool: &ThreadPool)

Runs the system/group of systems. Possibly in parallel depending on how the structure is set up.

fn reads(&self, reads: &mut Vec<ResourceId>)

Accumulates the necessary read/shared resources from the systems in this group.

fn writes(&self, writes: &mut Vec<ResourceId>)

Accumulates the necessary write/exclusive resources from the systems in this group.
