Struct SessionInfoDelta

SessionInfoDelta holds a description of a media session.

Fields

domain: Option<String>

The domain on which the session takes place. A domain identifies a set of mutually compatible media targets and sessions; sessions on a domain may be played back on targets of the same domain.

This field is always present.

is_local: Option<bool>

Whether the source of the media playback is on this device.

This field is present only if known.

is_locally_active: Option<bool>

If this is true, the playback is taking place local to the device. Playing on the device speaker is local, playing on a remote speaker is not. This is only set when the session is playing back; a paused session is not active.

This field is always present.

player_status: Option<PlayerStatus>

The status of the player.

This field is always present.

metadata: Option<Metadata>

Metadata describing the media session.

This field is always present.

media_images: Option<Vec<MediaImage>>

Images associated with the media or its source.

This field is always present.

player_capabilities: Option<PlayerCapabilities>

The capabilities the player of the media implements.

This field is always present.

Trait Implementations

impl Clone for SessionInfoDelta

fn clone(&self) -> SessionInfoDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SessionInfoDelta

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

Formats the value using the given formatter.

impl<D> Decode<SessionInfoDelta, D> for SessionInfoDelta

where D: ResourceDialect,

fn new_empty() -> SessionInfoDelta

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for SessionInfoDelta

fn default() -> SessionInfoDelta

Returns the “default value” for a type.

impl<D> Encode<SessionInfoDelta, D> for &SessionInfoDelta

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for SessionInfoDelta

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

impl TypeMarker for SessionInfoDelta

type Owned = SessionInfoDelta

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for SessionInfoDelta

type Borrowed<'a> = &'a SessionInfoDelta

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<SessionInfoDelta as TypeMarker>::Owned, ) -> <SessionInfoDelta as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
