Enum ChurnWindow 

pub enum ChurnWindow {
    Relative {
        count: u64,
        unit: ChurnWindowUnit,
    },
    Date(String),
    Imported,
}

The span of history churn analysis covers.

A relative window is stored as its duration rather than as the wall-clock string git resolves, so the same token always keys the same cache entry while the cutoff it resolves to moves with the run clock.

Variants

Relative

A span measured back from the run clock.

Fields

count: u64

How many units of history to cover.

unit: ChurnWindowUnit

The unit count is measured in.

Date(String)

An absolute ISO YYYY-MM-DD date, read as UTC midnight.

Imported

No window: imported churn covers whatever the exporter selected.

Implementations

impl ChurnWindow

pub fn cache_token(&self) -> String

Stable cache key for this window. Absolute for a date, the duration token ("1y", "90d") for a relative span.

pub fn cutoff_secs(&self, clock: &AnalysisClock) -> Option<u64>

The oldest commit timestamp this window includes, resolved against clock. None for imported churn, which has no cutoff to apply.
