Expand description

Trait for distance computation with compile-time dispatch

Required Methods§

Source

fn distance(a: &[f32], b: &[f32]) -> f32

Compute distance between two vectors (for comparisons, may skip sqrt for L2)

Source

fn to_actual(d: f32) -> f32

Convert comparison distance to actual distance (applies sqrt for L2)

Source

fn as_enum() -> DistanceFunction

Get the enum variant for runtime dispatch when needed

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.
