Trait IoBuf 

pub unsafe trait IoBuf: Unpin + 'static {
    // Required methods
    fn stable_ptr(&self) -> *const u8;
    fn bytes_init(&self) -> usize;
    fn bytes_total(&self) -> usize;
}

Required Methods

fn stable_ptr(&self) -> *const u8

Returns a raw pointer to the vector’s buffer.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

The implementation must ensure that, while the tokio-uring runtime owns the value, the pointer returned by stable_ptr does not change.

fn bytes_init(&self) -> usize

Number of initialized bytes.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

For Vec, this is identical to len().

fn bytes_total(&self) -> usize

Total size of the buffer, including uninitialized memory, if any.

This method is to be used by the tokio-uring runtime and it is not expected for users to call it directly.

For Vec, this is identical to capacity().

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
