Struct linux::time::timer::Timer

pub struct Timer { /* fields omitted */ }

A timer.

Methods

impl Timer

pub fn disable(&self) -> Result

Disables the timer.

pub fn interval(&self, iv: Time) -> Result

Sets the timer to expire every iv time units.

pub fn interval_from(&self, iv: Time, start: Time) -> Result

Sets the timer to expire every iv time units, starting at the absolute start.

pub fn interval_in(&self, iv: Time, when: Time) -> Result

Sets the timer to expire every iv time units, starting in when units.

pub fn once_at(&self, when: Time) -> Result

Sets the timer to expire once at the absolute when.

pub fn once_in(&self, when: Time) -> Result

Sets the timer to expire in when time units.

pub fn status(&self) -> Result<(Time, Time)>

Returns the status of the timer.

TODO: Document this.

pub fn ticks(&self) -> Result<u64>

Returns the number of times the timer expired since this function was last called.

Trait Implementations

impl FdContainer for Timer

fn is_owned(&self) -> bool

Returns whether the object owns the file descriptor, i.e., whether it closes it when it goes out of scope.

fn borrow(&self) -> c_int

Returns the contained file descriptor.

fn from_owned(fd: c_int) -> Timer

Creates a new owned object from a file descriptor.

fn from_borrowed(fd: c_int) -> Timer

Creates a new borrowed object from a file descriptor.

Important traits for FdIo

fn as_fdio(&self) -> FdIo

Borrows the file descriptor as an FdIo.

fn is_close_on_exec(&self) -> Result<bool>

Retrieves the status of the close on exec flag.

fn set_close_on_exec(&self, val: bool) -> Result

Enables or disables the close on exec flag.

fn description_flags(&self) -> Result<DescriptionFlags>

Retrieves the file description flags.

fn set_description_flags(&self, flags: DescriptionFlags) -> Result

Sets the file description flags.

fn duplicate(&self) -> Result<Self> where
    Self: Sized, 

Duplicates the file descriptor.

fn duplicate_min(&self, min: c_int) -> Result<Self> where
    Self: Sized, 

Duplicates the file descriptor so that the duplicated one has a minimum value.

fn duplicate_as(&self, new: c_int) -> Result<Self> where
    Self: Sized, 

Duplicates the file descriptor, replacing an existing one.

impl Drop for Timer

fn drop(&mut self)

Executes the destructor for this type.

impl From<Timer> for c_int

fn from(timer: Timer) -> Self

Performs the conversion.
