Union rustix::io_uring::io_uring_user_data

#[repr(C)]
pub union io_uring_user_data {
    pub u64_: u64,
    pub ptr: io_uring_ptr,
}

Available on crate feature io_uring only.

User data in the io_uring API.

io_uring’s native API represents user_data fields as u64 values. In order to preserve strict-provenance, use a union which allows users to optionally store pointers.

Fields

u64_: u64

An arbitrary u64.

ptr: io_uring_ptr

A pointer.

Implementations

impl io_uring_user_data

pub fn u64_(self) -> u64

Return the u64 value.

pub fn from_u64(u64_: u64) -> Self

Create a Self from a u64 value.

pub fn ptr(self) -> *mut c_void

Return the ptr pointer value.

pub fn from_ptr(ptr: *mut c_void) -> Self

Create a Self from a pointer value.
