Struct OperationFuture 

pub struct OperationFuture<'ring, 'buf> { /* private fields */ }

Generic future for any operation type.

This provides a unified interface for different operation types while maintaining type safety and proper buffer ownership semantics. Unlike the specialized I/O futures, this returns the raw i32 result from io_uring without conversion to usize.

Type Parameters

• 'ring - Lifetime of the io_uring instance
• 'buf - Lifetime of the buffer being used for the operation

Returns

Returns (i32, Option<Pin<&'buf mut [u8]>>) where:

• i32 is the raw result from io_uring (can be negative for errors)
• Option<Pin<&'buf mut [u8]>> is the buffer if the operation used one

Trait Implementations

impl<'ring, 'buf> Drop for OperationFuture<'ring, 'buf>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<'ring, 'buf> Future for OperationFuture<'ring, 'buf>

type Output = Result<(i32, Option<Pin<&'buf mut [u8]>>), Error>

The type of value produced on completion.

fn poll(self: StdPin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
