zxfoundation.sync.waitqueue.types Module Reference

Data Structures
struct	zxfoundation::sync::waitqueue::wait_entry
	Intrusive wait queue entry — embedded in the waiter's stack frame. More...
struct	zxfoundation::sync::waitqueue::wait_head
	Wait queue — a spinlock-protected list of wait_entry nodes. More...

Enumerations
enum class	wait_flags : u32 { none = 0 , exclusive = 1U << 0 , interruptible = 1U << 1 }
	Per-waiter behavioural flags (bitfield).
enum class	wait_result : u8 { woken = 0 , timeout = 1 , interrupted = 2 }
	Outcome of a wait operation.
