Struct StreamProperties2

pub struct StreamProperties2 {
    pub image_format: Option<ImageFormat2>,
    pub frame_rate: Option<FrameRate>,
    pub supports_crop_region: Option<bool>,
    pub supported_resolutions: Option<Vec<Size>>,
    /* private fields */
}

Describes the properties of a given stream.

Fields

image_format: Option<ImageFormat2>

Describes the native image format used by a stream.

frame_rate: Option<FrameRate>

Describes the framerate used by a stream.

supports_crop_region: Option<bool>

Indicates whether a stream supports the SetCropRegion method.

supported_resolutions: Option<Vec<Size>>

Describes the precise resolutions supported by a stream, i.e. those for which SetResolution results in a WatchResolution callback of the same value. If empty, it indicates that the stream supports arbitrary resolutions. If non-empty, the list contains at least one element reflecting the native resolution specified by |image_format|.

Trait Implementations

impl Clone for StreamProperties2

fn clone(&self) -> StreamProperties2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StreamProperties2

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

Formats the value using the given formatter.

impl<D> Decode<StreamProperties2, D> for StreamProperties2

where D: ResourceDialect,

fn new_empty() -> StreamProperties2

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 StreamProperties2

fn default() -> StreamProperties2

Returns the “default value” for a type.

impl<D> Encode<StreamProperties2, D> for &StreamProperties2

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 StreamProperties2

fn eq(&self, other: &StreamProperties2) -> 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 StreamProperties2

type Owned = StreamProperties2

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 StreamProperties2

type Borrowed<'a> = &'a StreamProperties2

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: &<StreamProperties2 as TypeMarker>::Owned, ) -> <StreamProperties2 as ValueTypeMarker>::Borrowed<'_>

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