Struct mpris_server::MaybePlaylist

pub struct MaybePlaylist { /* private fields */ }

A data structure describing a playlist, or nothing.

Rationale

D-Bus does not (at the time of writing) support a MAYBE type, so we are forced to invent our own.

Implementations

impl MaybePlaylist

pub fn just(playlist: Playlist) -> Self

Construct a valid MaybePlaylist from the given playlist.

pub fn nothing() -> Self

Construct a MaybePlaylist that contains invalid/no playlist.

The playlist ID will be set to “/”, and the name and icon will be empty.

pub fn get(&self) -> Option<&Playlist>

Returns Some if this structure contains a valid playlist, otherwise None.

Trait Implementations

impl Clone for MaybePlaylist

fn clone(&self) -> MaybePlaylist

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MaybePlaylist

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

Formats the value using the given formatter.

impl From<MaybePlaylist> for Option<Playlist>

fn from(mp: MaybePlaylist) -> Self

Converts to this type from the input type.

impl<'a> From<MaybePlaylist> for Value<'a>

fn from(mp: MaybePlaylist) -> Self

Converts to this type from the input type.

impl From<Option<Playlist>> for MaybePlaylist

fn from(opt: Option<Playlist>) -> Self

Converts to this type from the input type.

impl From<Playlist> for MaybePlaylist

fn from(playlist: Playlist) -> Self

Converts to this type from the input type.

impl PartialEq<MaybePlaylist> for MaybePlaylist

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

impl Serialize for MaybePlaylist

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Type for MaybePlaylist

fn signature() -> Signature<'static>

Get the signature for the implementing type.
