Enum ExpressionVariant 

pub enum ExpressionVariant {
    Invalid,
    Boolean(bool),
    Double(f64),
    Vector2(Vector2),
    Vector3(Vector3),
    Vector4(Vector4),

    Quaternion(Quaternion),
    Color(Color),
    RelativePoint(RelativePoint),
    RelativeScalar(RelativeScalar),
    RelativeUnit(RelativeUnit),
}

A VARIANT type used in expression animations. Can represent multiple value types.

Every operation that is not defined for its operand types gives ExpressionVariant::Invalid rather than failing.

Implementations

impl ExpressionVariant

pub fn variant_type(&self) -> VariantType

The type of the held value.

pub fn get_property(&self, property: &str) -> ExpressionVariant

Gets a member (a component or a swizzle) of the held value. Member names are case-sensitive; an unknown member gives Invalid.

pub fn equals_to(&self, right: ExpressionVariant) -> ExpressionVariant

The == operator of expressions: a Boolean for two values of the same comparable type, Invalid otherwise.

pub fn not_equals_to(&self, right: ExpressionVariant) -> ExpressionVariant

The != operator of expressions.

pub fn less_than(&self, right: ExpressionVariant) -> ExpressionVariant

The < operator of expressions.

pub fn more_than(&self, right: ExpressionVariant) -> ExpressionVariant

The > operator of expressions.

pub fn and(&self, right: ExpressionVariant) -> ExpressionVariant

The && operator of expressions.

pub fn or(&self, right: ExpressionVariant) -> ExpressionVariant

The || operator of expressions.

pub fn try_cast<T: ExpressionVariantValue>(&self) -> Option<T>

Converts the held value to T, or None when the variant does not hold a value convertible to T.

pub fn create<T: ExpressionVariantValue>(v: T) -> ExpressionVariant

Creates a variant from a value.

pub fn cast_or_default<T: ExpressionVariantValue>(&self) -> T

Converts the held value to T, or gives the default value of T.
