Enum lightningcss::values::angle::Angle

pub enum Angle {
    Deg(CSSNumber),
    Rad(CSSNumber),
    Grad(CSSNumber),
    Turn(CSSNumber),
}

A CSS <angle> value.

Angles may be explicit or computed by calc(), but are always stored and serialized as their computed value.

Variants

Deg(CSSNumber)

An angle in degrees. There are 360 degrees in a full circle.

Rad(CSSNumber)

An angle in radians. There are 2π radians in a full circle.

Grad(CSSNumber)

An angle in gradians. There are 400 gradians in a full circle.

Turn(CSSNumber)

An angle in turns. There is 1 turn in a full circle.
