Struct Pollfd

pub struct Pollfd { /* private fields */ }

Implementations

impl Pollfd

pub fn new( fd: c_int, events: c_short, revents: c_short, ) -> Result<Self, AeronCError>

pub fn new_zeroed() -> Result<Self, AeronCError>

creates zeroed struct where the underlying c struct is on the heap

pub fn fd(&self) -> c_int

pub fn events(&self) -> c_short

pub fn revents(&self) -> c_short

pub fn aeron_poll( &self, nfds: c_ulong, timeout: c_int, ) -> Result<i32, AeronCError>

pub fn get_inner(&self) -> *mut pollfd

impl Pollfd

pub fn clone_struct(&self) -> Self

Regular clone just increases the reference count of underlying count. clone_struct shallow copies the content of the underlying struct on heap.

NOTE: if the struct has references to other structs these will not be copied

Must be only used on structs which has no init/clean up methods. So its danagerous to use with Aeron/AeronContext/AeronPublication/AeronSubscription More intended for AeronArchiveRecordingDescriptor

Trait Implementations

impl Clone for Pollfd

fn clone(&self) -> Pollfd

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pollfd

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Pollfd

This will create an instance where the struct is zeroed, use with care

fn default() -> Self

Returns the “default value” for a type.

impl Deref for Pollfd

type Target = pollfd

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
