}Expand description
Abstraction of io-uring operations.
§Safety
The returned Entry from create_entry must be valid until the operation is
completed.
Required Methods§
Sourcefn create_entry(self: Pin<&mut Self>) -> OpEntry
fn create_entry(self: Pin<&mut Self>) -> OpEntry
Create submission entry.
Provided Methods§
Sourcefn call_blocking(self: Pin<&mut Self>) -> Result<usize>
fn call_blocking(self: Pin<&mut Self>) -> Result<usize>
Call the operation in a blocking way. This method will only be called if
create_entry returns OpEntry::Blocking.
Sourceunsafe fn set_result(self: Pin<&mut Self>, _: usize)
unsafe fn set_result(self: Pin<&mut Self>, _: usize)
Set the result when it successfully completes. The operation stores the result and is responsible to release it if the operation is cancelled.
§Safety
Users should not call it.
