Implementations

impl MediaTrackConstraint

pub fn is_empty(&self) -> bool

Returns true if self is empty, otherwise false.

pub fn to_resolved( &self, strategy: MediaTrackConstraintResolutionStrategy, ) -> ResolvedMediaTrackConstraint

Returns a resolved representation of the constraint with bare values resolved to fully-qualified constraints.

pub fn into_resolved( self, strategy: MediaTrackConstraintResolutionStrategy, ) -> ResolvedMediaTrackConstraint

Consumes the constraint, returning a resolved representation of the constraint with bare values resolved to fully-qualified constraints.
