Expand description

Trait for scoring paths based on specific metrics.

Implementors provide a method to score a path, returning a floating point score between -1.0 and 1.0. Higher scores indicate more preferred paths.

Scores from multiple implementations are aggregated to form a composite path score, which is used for selecting a preferred path.

Required Methods§

Source

fn metric_name(&self) -> &'static str

Name of the metric being scored. Used for debugging path scoring decisions.

Source

fn score(&self, path: &PathManagerPath, now: SystemTime) -> Score

Scores the given path, returning a floating point score.

Higher scores indicate more preferred paths.

path - The path to score. now - The current system time for time sensitive scores.
