The signal manager. You don’t need to create one by yourself.

Implementations§

Source§

impl SignalManager

Source

pub fn new(signal_type_num: usize) -> Self

Source

pub fn has_signal(&self, signal_type: usize) -> bool

Returns whether the signal type is registered.

Source

pub fn register_signal(&mut self, signal_type: usize, signal: Signal) -> bool

Registers a new signal and wakes up the process if it is waiting for the signal.

Source

pub fn register_wait_for(&mut self, signal_type: usize)

Starts to wait for a signal.

Source

pub fn get_signal(&mut self, signal_type: usize) -> Option<Signal>

Gets a signal of the specified type. Returns None if the signal type is not registered.

Source

pub fn delete_signal(&mut self, signal_type: usize)

Deletes a signal of the specified type. Nothing happens if the signal type is not registered.
