Union rustix::event::epoll::EventData

#[repr(C)]
pub union EventData {
    /* private fields */
}

Data associated with an Event. This can either be a 64-bit integer value or a pointer which preserves pointer provenance.

Implementations

impl EventData

pub const fn new_u64(value: u64) -> Self

Construct a new value containing a u64.

pub const fn new_ptr(value: *mut c_void) -> Self

Construct a new value containing a *mut c_void.

pub fn u64(self) -> u64

Return the value as a u64.

If the stored value was a pointer, the pointer is zero-extended to a u64.

pub fn ptr(self) -> *mut c_void

Return the value as a *mut c_void.

If the stored value was a u64, the least-significant bits of the u64 are returned as a pointer value.

Trait Implementations

impl Clone for EventData

fn clone(&self) -> EventData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for EventData

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EventData

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
