Trait Implementations

impl Clone for spa_system_methods

fn clone(&self) -> spa_system_methods

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for spa_system_methods

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

Formats the value using the given formatter.

impl PartialEq<spa_system_methods> for spa_system_methods

fn eq(&self, other: &spa_system_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.
