[−][src]Struct thread_tree::ThreadTreeCtx
A level-specific handle to the thread tree, that can be used to inject jobs.
See ThreadTree::top()
for more information.
Implementations
impl<'_> ThreadTreeCtx<'_>
[src][−]
pub fn is_parallel(&self) -> bool
[src][−]
Return true if this level will parallelize in join (or if we are at the bottom of the tree)
pub fn join<A, B, RA, RB>(&self, a: A, b: B) -> (RA, RB) where
A: FnOnce(ThreadTreeCtx<'_>) -> RA + Send,
B: FnOnce(ThreadTreeCtx<'_>) -> RB + Send,
RA: Send,
RB: Send,
[src][−]
A: FnOnce(ThreadTreeCtx<'_>) -> RA + Send,
B: FnOnce(ThreadTreeCtx<'_>) -> RB + Send,
RA: Send,
RB: Send,
Run a and b simultaneously (and return their results, if applicable).
A runs on the current thread while b runs on the sibling thread; each is passed a lower level of the thread tree (if applicable, or a stub if the bottom is reached).
Warning: functions that execute on worker threads here must not panic (it will abort on panic). Out of a and b, at most one will execute on a worker thread from here, and at least one (or both) will execute on the current thread.
Warning: You must not .join() into the same tree from nested jobs. Nested jobs must be spawned using the context that each job receives as the first parameter.
