Trait Implementations

impl Clone for playdate_sound_track

fn clone(&self) -> playdate_sound_track

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for playdate_sound_track

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

Formats the value using the given formatter.

impl Default for playdate_sound_track

fn default() -> playdate_sound_track

Returns the “default value” for a type.

impl PartialEq for playdate_sound_track

fn eq(&self, other: &playdate_sound_track) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
