Struct SupportedEncodings 

pub struct SupportedEncodings {
    pub channel_sets: Option<Vec<ChannelSet>>,
    pub frame_rates: Option<Vec<u32>>,
    pub encoding_types: Option<Vec<EncodingType>>,
    /* private fields */
}

Supported formats for encoded audio.

This table defines a valid set of configurations. All fields are independent, which implies a cross-product: any listed channel_set is supported at any listed frame_rate for any listed encoded_type.

If a device supports multiple encoders with different rate/channel constraints (e.g. AAC supports 48kHz but SBC only supports 44.1kHz), the device must report them as separate entries in the SupportedFormats vector.

Fields

channel_sets: Option<Vec<ChannelSet>>

Vector of possible ChannelSets supported. A ChannelSet specifies a channel configuration (including a channel-count), plus a number of optional attributes.

Each entry in this vector must describe a unique channel count. For example, this vector cannot contain two different ChannelSet entries that both apply to a 2-channel configuration.

Required.

frame_rates: Option<Vec<u32>>

Vector of possible frame rates supported. Values must be listed in ascending order.

Required.

encoding_types: Option<Vec<EncodingType>>

The encoder types that support the configurations listed above.

Required.

Trait Implementations

impl Clone for SupportedEncodings

fn clone(&self) -> SupportedEncodings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SupportedEncodings

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

Formats the value using the given formatter.

impl<D> Decode<SupportedEncodings, D> for SupportedEncodings

where D: ResourceDialect,

fn new_empty() -> SupportedEncodings

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 SupportedEncodings

fn default() -> SupportedEncodings

Returns the “default value” for a type.

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

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 SupportedEncodings

fn eq(&self, other: &SupportedEncodings) -> 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 SupportedEncodings

type Owned = SupportedEncodings

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 SupportedEncodings

type Borrowed<'a> = &'a SupportedEncodings

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

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