Trait style::values::animated::ToAnimatedZero

pub trait ToAnimatedZero: Sized {
    // Required method
    fn to_animated_zero(&self) -> Result<Self, ()>;
}

Expand description

Returns a value similar to self that represents zero.

This trait is derivable with #[derive(ToAnimatedValue)]. If a field is annotated with #[animation(constant)], a clone of its value will be used instead of calling ToAnimatedZero::to_animated_zero on it.

If a variant is annotated with #[animation(error)], the corresponding match arm is not generated.

Trait bounds for type parameter Foo can be opted out of with #[animation(no_bound(Foo))] on the type definition.

Required Methods§

source

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

This is not the necessarily the same as the initial value of a property. For example, the initial value of ‘stroke-width’ is 1, but the zero value is 0, since adding 1 to the underlying value will not produce the underlying value.
