    pub ph: f64,
    pub k: usize,

Expand description

Coding parameters computed for a specific network state and target Ph.

Stored in the FileManifest at upload time and used by the daemon to determine how many fragments to generate and distribute per chunk.

Fields§

§ph: f64

Target recovery probability requested at computation time.

§k: usize

Recovery threshold: the minimum fragments needed to reconstruct a chunk.

§n: usize

Total fragments to generate per chunk (= k + redundancy).

§q: f64

Effective redundancy overhead: (n − k) / k.

§peer_count: usize

Number of Pouch peers considered in this computation.

§mu: f64

Poisson-Binomial mean μ = Σ p_i.

§sigma: f64

Poisson-Binomial std-dev σ = sqrt(Σ p_i·(1−p_i)).

Implementations§

Source §

impl NetworkCodingParams

Source

pub fn effective_probability(&self) -> f64

Effective recovery probability given the same set of stability scores.

Useful for re-evaluating pe with updated QoS data after upload.
