Implementations

impl ResolvedMediaTrackConstraint

pub fn exact_from(setting: MediaTrackSetting) -> Self

Creates a resolved media track constraint by resolving bare values to exact constraints: { exact: bare }.

pub fn ideal_from(setting: MediaTrackSetting) -> Self

Creates a resolved media track constraint by resolving bare values to ideal constraints: { ideal: bare }.

pub fn is_required(&self) -> bool

Returns true if self is required, otherwise false.

pub fn is_empty(&self) -> bool

Returns true if self is empty, otherwise false.

pub fn to_required_only(&self) -> Self

Returns a corresponding constraint containing only required values.

pub fn into_required_only(self) -> Self

Consumes `self, returning a corresponding constraint containing only required values.

pub fn to_sanitized(&self) -> Option<SanitizedMediaTrackConstraint>

Returns a corresponding sanitized constraint if self is non-empty, otherwise None.

pub fn into_sanitized(self) -> Option<SanitizedMediaTrackConstraint>

Consumes self, returning a corresponding sanitized constraint if self is non-empty, otherwise None.

Trait Implementations

impl Clone for ResolvedMediaTrackConstraint

fn clone(&self) -> ResolvedMediaTrackConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ResolvedMediaTrackConstraint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ResolvedMediaTrackConstraint
