Fields

version: u32

get_interface: Option<unsafe extern "C" fn(handle: *mut spa_handle, type_: *const c_char, interface: *mut *mut c_void) -> c_int>

Get the interface provided by \a handle with \a type.

\a interface is always a struct spa_interface but depending on \a type, the struct might contain other information.

\param handle a spa_handle \param type the interface type \param interface result to hold the interface. \return 0 on success -ENOTSUP when there are no interfaces -EINVAL when handle or info is NULL

clear: Option<unsafe extern "C" fn(handle: *mut spa_handle) -> c_int>

Clean up the memory of \a handle. After this, \a handle should not be used anymore.

\param handle a pointer to memory \return 0 on success

Trait Implementations

impl Clone for spa_handle

fn clone(&self) -> spa_handle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for spa_handle

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

Formats the value using the given formatter.

impl PartialEq for spa_handle

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