Struct libspa_sys::spa_loop_control_hooks

#[repr(C)]
pub struct spa_loop_control_hooks {
    pub version: u32,
    pub before: Option<unsafe extern "C" fn(data: *mut c_void)>,
    pub after: Option<unsafe extern "C" fn(data: *mut c_void)>,
}

Control hooks. These hooks can’t be removed from their callbacks and must be removed from a safe place (when the loop is not running or when it is locked).

Fields

version: u32

before: Option<unsafe extern "C" fn(data: *mut c_void)>

Executed right before waiting for events. It is typically used to release locks.

after: Option<unsafe extern "C" fn(data: *mut c_void)>

Executed right after waiting for events. It is typically used to reacquire locks.

Trait Implementations

impl Clone for spa_loop_control_hooks

fn clone(&self) -> spa_loop_control_hooks

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for spa_loop_control_hooks

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

Formats the value using the given formatter.

impl PartialEq for spa_loop_control_hooks

fn eq(&self, other: &spa_loop_control_hooks) -> 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.
