Methods
impl Parameters[src]
pub fn is_setup_sqpoll(&self) -> bool[src]
pub fn is_setup_iopoll(&self) -> bool[src]
pub fn is_feature_single_mmap(&self) -> bool[src]
If this flag is set, the two SQ and CQ rings can be mapped with a single mmap(2) call.
The SQEs must still be allocated separately.
This brings the necessary mmap(2) calls down from three to two.
pub fn is_feature_nodrop(&self) -> bool[src]
If this flag is set, io_uring supports never dropping completion events. If a completion event occurs and the CQ ring is full, the kernel stores the event internally until such a time that the CQ ring has room for more entries.
pub fn is_feature_submit_stable(&self) -> bool[src]
If this flag is set, applications can be certain that any data for async offload has been consumed when the kernel has consumed the SQE
