Trait emf_core_base_rs_ffi::sys::sync_handler::SyncHandlerBinding

pub trait SyncHandlerBinding {
    unsafe fn lock(&self);
    unsafe fn try_lock(&self) -> Bool;
    unsafe fn unlock(&self);
}

Helper trait for using a sync handler.

Required methods

unsafe fn lock(&self)

Locks the synchronisation handler.

The calling thread is stalled until the lock can be acquired. Only one thread can hold the lock at a time.

Safety

The function crosses the ffi boundary. Direct usage of a SyncHandlerBinding may break some invariants of the sys api, if not handled with care.

unsafe fn try_lock(&self) -> Bool

Tries to lock the synchronisation handler.

The function fails if another thread already holds the lock.

Return

Bool::True on success and Bool::False otherwise.

Safety

The function crosses the ffi boundary. Direct usage of a SyncHandlerBinding may break some invariants of the sys api, if not handled with care.

unsafe fn unlock(&self)

Unlocks the synchronisation handler.

Safety

The function crosses the ffi boundary. Trying to call this function without prior locking is undefined behaviour. Direct usage of a SyncHandlerBinding may break some invariants of the sys api, if not handled with care.
