Struct sgx_tstd::sync::Barrier [−][src]
pub struct Barrier { /* fields omitted */ }
A barrier enables multiple threads to synchronize the beginning of some computation.
Methods
impl Barrier
[src]
impl Barrier
pub fn new(n: usize) -> Barrier
[src]
pub fn new(n: usize) -> Barrier
Creates a new barrier that can block a given number of threads.
A barrier will block n
-1 threads which call [wait
] and then wake up
all threads at once when the n
th thread calls [wait
].
pub fn wait(&self) -> BarrierWaitResult
[src]
pub fn wait(&self) -> BarrierWaitResult
Blocks the current thread until all threads have rendezvoused here.
Barriers are re-usable after all threads have rendezvoused once, and can be used continuously.
A single (arbitrary) thread will receive a BarrierWaitResult
that
returns true
from [is_leader
] when returning from this function, and
all other threads will receive a result that will return false
from
[is_leader
].
