pub struct SettableElementState {
    pub type_specific: Option<SettableTypeSpecificElementState>,

}

Processing element state that can be set by clients.

Fields

type_specific: Option<SettableTypeSpecificElementState>

Type-specific state parameters for the processing element.

If this processing element is disabled and its type-specific state is provided, then the type-specific state is only informational, for instance if a SetElementState enables a disabled processing element providing a SettableTypeSpecificElementState, then any previous informational SettableTypeSpecificElementState is superceded.

If not set, then the element’s previous type_specific state will be unchanged.

Optional for Dynamics, Equalizer, Gain and VendorSpecific types. Invalid if included for any other element type.

vendor_specific_data: Option<Vec<u8>>

If included, an opaque object of octets for exchanging vendor specific information. This can send vendor-specific data to any element, not just the VendorSpecific type.

Optional.

started: Option<bool>

Whether to start this processing element (or to stop it, if false). A stopped processing element does not provide its abstracted functionality. Specifically, no audio data flows through a stopped element.

If the corresponding Element returned can_stop equals to false, then this field must not be set to false. If not set, then the element’s previous started state will be unchanged.

Optional.

bypassed: Option<bool>

Whether to bypass this processing element (or to enable/“unbypass” it, if false). A bypassed element does not affect the flow of audio through the topology. Specifically, audio flows through the element without any change.

If the corresponding Element contains a can_bypass of false, then this field must not be set to true. If not set, then the element’s previous bypassed state will be unchanged.

Optional.

Trait Implementations

impl Clone for SettableElementState

fn clone(&self) -> SettableElementState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SettableElementState

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<SettableElementState, D> for SettableElementState

fn new_empty() -> Self

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<()>

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

impl Default for SettableElementState

fn default() -> SettableElementState

Returns the “default value” for a type.

impl<D: ResourceDialect> Encode<SettableElementState, D> for &SettableElementState

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

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

impl PartialEq for SettableElementState

fn eq(&self, other: &SettableElementState) -> 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 TypeMarker for SettableElementState

type Owned = SettableElementState

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 SettableElementState

type Borrowed<'a> = &'a SettableElementState

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: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

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