Expand description
Calculate the distance between two colors as if they were coordinates in Euclidean space.
Euclidean distance is not always a good measurement of visual color
difference, depending on the color space. Some spaces, like
Lab
and Oklab
, will give a fairly uniform
result, while other spaces, such as Rgb
, will give much
less uniform results. Despite that, it’s still appropriate for some
applications.

sourcefn distance_squared(self, other: Self) -> Self::Scalar
fn distance_squared(self, other: Self) -> Self::Scalar
Calculate the squared Euclidean distance from self
to other
.
This is typically a faster option than Self::distance
for some
cases, such as when comparing two distances.
