Enum ValueRangeConstraint

Source
pub enum ValueRangeConstraint<T> {
    Bare(T),
    Constraint(ResolvedValueRangeConstraint<T>),
}
Expand description

A bare value or constraint specifying a range of accepted values.

§W3C Spec Compliance

There exists no direct corresponding type in the W3C “Media Capture and Streams” spec, since the ValueConstraint<T> type aims to be a generalization over multiple types in the spec.

Variants§

§

Bare(T)

A bare-valued media track constraint.

§

Constraint(ResolvedValueRangeConstraint<T>)

A fully-qualified media track constraint.
