Trait cogset::Point [−] [src]

pub trait Point {
    fn dist(&self, other: &Self) -> f64;

    fn dist_lower_bound(&self, other: &Self) -> f64 { ... }
}

A point in some (metric) space.

Required Methods

Accurate compute the distance from self to other.

This should be real and non-negative, or else algorithms may return unexpected results.

Compute an estimate of the distance from self to other.

This should be less than or equal to self.dist(other) or else algorithms may return unexpected results.
