Struct DisplayVideoTrackConstraints 

pub struct DisplayVideoTrackConstraints {
    pub required: bool,
    pub device_id: Option<ConstrainString<String>>,
    pub height: Option<ConstrainU32>,
    pub width: Option<ConstrainU32>,
    pub frame_rate: Option<ConstrainU32>,
}

Constraints applicable to video tracks sourced from a screen capturing.

Fields

required: bool

Importance of this DisplayVideoTrackConstraints.

If true then without these DisplayVideoTrackConstraints a session call can’t be started.

device_id: Option<ConstrainString<String>>

Identifier of the device generating the content for the media track.

height: Option<ConstrainU32>

Height of the video in pixels.

width: Option<ConstrainU32>

Width of the video in pixels.

frame_rate: Option<ConstrainU32>

Frame rate of the video.

Implementations

impl DisplayVideoTrackConstraints

pub fn new() -> Self

Creates new DisplayVideoTrackConstraints with none constraints configured.

pub async fn satisfies<T: AsRef<MediaStreamTrack>>(&self, track: T) -> bool

Checks whether the provided platform::MediaStreamTrack satisfies contained DisplayVideoTrackConstraints.

pub fn merge(&mut self, another: Self)

Merges these DisplayVideoTrackConstraints with another ones, meaning that if some constraints are not set on these, then they will be applied from another.

pub const fn exact_height(&mut self, height: u32)

Sets an exact height constraint.

pub const fn ideal_height(&mut self, height: u32)

Sets an ideal height constraint.

pub const fn exact_width(&mut self, width: u32)

Sets an exact width constraint.

pub const fn ideal_width(&mut self, width: u32)

Sets an ideal width constraint.

pub fn device_id(&mut self, device_id: String)

Sets an exact deviceId constraint.

pub const fn exact_frame_rate(&mut self, frame_rate: u32)

Sets an exact frameRate constraint.

pub const fn ideal_frame_rate(&mut self, frame_rate: u32)

Sets an ideal frameRate constraint.

pub const fn required(&self) -> bool

Returns an importance of this DisplayVideoTrackConstraints.

If these DisplayVideoTrackConstraints are important then without them a session call can’t be started.

Trait Implementations

impl Clone for DisplayVideoTrackConstraints

fn clone(&self) -> DisplayVideoTrackConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayVideoTrackConstraints

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

Formats the value using the given formatter.

impl Default for DisplayVideoTrackConstraints

fn default() -> DisplayVideoTrackConstraints

Returns the “default value” for a type.

impl From<ApiDisplayVideoTrackConstraints> for DisplayVideoTrackConstraints

fn from(value: ApiDisplayVideoTrackConstraints) -> Self

Converts to this type from the input type.

impl From<DisplayVideoTrackConstraints> for MediaTrackConstraints

fn from(from: DisplayVideoTrackConstraints) -> Self

Converts to this type from the input type.

impl PartialEq for DisplayVideoTrackConstraints

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