Register sources and work items to an event loop

Fields

version: u32

add_source: Option<unsafe extern "C" fn(object: *mut c_void, source: *mut spa_source) -> c_int>

add a source to the loop

update_source: Option<unsafe extern "C" fn(object: *mut c_void, source: *mut spa_source) -> c_int>

update the source io mask

remove_source: Option<unsafe extern "C" fn(object: *mut c_void, source: *mut spa_source) -> c_int>

remove a source from the loop

invoke: Option<unsafe extern "C" fn(object: *mut c_void, func: spa_invoke_func_t, seq: u32, data: *const c_void, size: usize, block: bool, user_data: *mut c_void) -> c_int>

invoke a function in the context of this loop

Trait Implementations

impl Clone for spa_loop_methods

fn clone(&self) -> spa_loop_methods

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for spa_loop_methods

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

Formats the value using the given formatter.

impl PartialEq for spa_loop_methods

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