Struct ResolvedValueSequenceConstraint

pub struct ResolvedValueSequenceConstraint<T> {
    pub exact: Option<Vec<T>>,
    pub ideal: Option<Vec<T>>,
}

A constraint specifying a sequence of accepted values.

W3C Spec Compliance

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

Rust	W3C
ResolvedValueSequenceConstraint<String>	ConstrainDOMStringParameters

Fields

exact: Option<Vec<T>>

The exact required value for this property.

This is a required value.

ideal: Option<Vec<T>>

The ideal (target) value for this property.

This is an optional value.

Implementations

impl<T> ResolvedValueSequenceConstraint<T>

pub fn exact<U>(self, exact: U) -> Self

where Option<Vec<T>>: From<U>,

Consumes self, returning a corresponding constraint with the exact required value set to exact.

pub fn ideal<U>(self, ideal: U) -> Self

where Option<Vec<T>>: From<U>,

Consumes self, returning a corresponding constraint with the ideal required value set to ideal.

pub fn is_required(&self) -> bool

Returns true if value.is_some() is true for any of its required values, otherwise false.

pub fn is_empty(&self) -> bool

Returns true if value.is_none() is true for all of its values, otherwise false.

pub fn to_required_only(&self) -> Self

where T: Clone,

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.
