Struct RankStats 

pub struct RankStats {
    pub count: usize,
    pub max_len: usize,
    pub total_len: usize,
}

Rank-length statistics used to decide whether Rank::rebalance is needed.

Fields

count: usize

Number of ranks to be aggregated.

max_len: usize

Maximum rank length in digits, the main indicator of rank-space expansion.

total_len: usize

Sum of all rank lengths (used to calculate average).

Implementations

impl RankStats

pub fn collect<'a, I>(ranks: I) -> RankStats

where I: IntoIterator<Item = &'a Rank>,

Traverse the rank column and aggregate statistics.

pub fn average_len(&self) -> f64

Return the average rank length, or 0.0 when no ranks were provided.

pub fn should_rebalance(&self, max_len_threshold: usize) -> bool

Return whether the maximum rank length exceeds max_len_threshold.
