pub trait ComputeSquaredDistance {
// Required method
fn compute_squared_distance(
&self,
other: &Self,
) -> Result<SquaredDistance, ()>;
}Expand description
A trait to compute squared distances between two animatable values.
This trait is derivable with #[derive(ComputeSquaredDistance)]. The derived
implementation uses a match expression with identical patterns for both
self and other, calling ComputeSquaredDistance::compute_squared_distance
on each fields of the values.
If a variant is annotated with #[animation(error)], the corresponding
match arm returns an error.
Trait bounds for type parameter Foo can be opted out of with
#[animation(no_bound(Foo))] on the type definition, trait bounds for
fields can be opted into with #[distance(field_bound)] on the field.
Required Methods§
Sourcefn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>
fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>
Computes the squared distance between two animatable values.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
