Enum AudioStreamSettingSource

#[repr(u32)]
pub enum AudioStreamSettingSource {
    User = 0,
    System = 1,
    SystemWithFeedback = 2,
}

The source of the volume settings. The volume is set according to the source.

Variants

User = 0

The volume is set by the user. When the source in AudioStreamSettings is set to this, the audio volume is set to user_volume.

System = 1

The system takes control of the volume. This is used when the system constantly calculates and changes the volume. The volume is not stored for this source.

SystemWithFeedback = 2

The system takes control of the volume. This is used when the system changes the volume, but we still want to play feedback sounds for these changes. The volume is not stored for this source.

Trait Implementations

impl Clone for AudioStreamSettingSource

fn clone(&self) -> AudioStreamSettingSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AudioStreamSettingSource

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

Formats the value using the given formatter.

impl<D> Decode<AudioStreamSettingSource, D> for AudioStreamSettingSource

where D: ResourceDialect,

fn new_empty() -> AudioStreamSettingSource

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<D> Encode<AudioStreamSettingSource, D> for AudioStreamSettingSource

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 Hash for AudioStreamSettingSource

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AudioStreamSettingSource

fn cmp(&self, other: &AudioStreamSettingSource) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AudioStreamSettingSource

fn eq(&self, other: &AudioStreamSettingSource) -> 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 PartialOrd for AudioStreamSettingSource

fn partial_cmp(&self, other: &AudioStreamSettingSource) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TypeMarker for AudioStreamSettingSource

type Owned = AudioStreamSettingSource

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 AudioStreamSettingSource

type Borrowed<'a> = AudioStreamSettingSource

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: &<AudioStreamSettingSource as TypeMarker>::Owned, ) -> <AudioStreamSettingSource as ValueTypeMarker>::Borrowed<'_>

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