Methods

impl Parameters

pub fn is_setup_sqpoll(&self) -> bool

pub fn is_setup_iopoll(&self) -> bool

pub fn is_feature_single_mmap(&self) -> bool

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

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

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

pub fn is_feature_rw_cur_pos(&self) -> bool

pub fn is_feature_cur_personality(&self) -> bool

pub fn sq_entries(&self) -> u32

pub fn cq_entries(&self) -> u32

Trait Implementations

impl Clone for Parameters

fn clone(&self) -> Parameters

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
