Enum EdgeCount 

pub enum EdgeCount {
    Exact(usize),
    Estimate {
        count: usize,
        min: usize,
        max: usize,
        sample_size: usize,
    },
    Unavailable,
}

Edge count representation.

Provides either an exact count or an estimate for large graphs where counting would be prohibitively expensive.

Variants

Exact(usize)

Exact edge count (for small to medium graphs)

Estimate

Estimated edge count with confidence interval

Fields

count: usize

Estimated count

min: usize

Lower bound of confidence interval

max: usize

Upper bound of confidence interval

sample_size: usize

Sample size used for estimation

Unavailable

Edge counting not available for this backend

Implementations

impl EdgeCount

pub fn value(&self) -> Option<usize>
