Struct PreRollInfo 

pub struct PreRollInfo {
    pub asked_s: f64,
    pub covered_s: f64,
    pub watched: Vec<String>,
    pub evicted: u64,
    pub expired: u64,
}

The retained window’s account of itself at trigger time (RFC 13 §4.3’s pre-roll bullet): what --pre asked for and what the ring could give.

Fields

asked_s: f64

The pre-roll the operator asked for, seconds.

covered_s: f64

The span the ring actually held when the trigger fired — shorter than asked_s while the ring was still filling, or when the byte budget bit (evicted).

watched: Vec<String>

The selectors the ring was fed under: the pre-roll covers these and nothing wider (O5).

evicted: u64

Samples the ring dropped because its byte budget bit — the window is then narrower than asked_s claims (O6).

expired: u64

Samples that aged past the pre-roll — the window sliding as declared, counted apart from evicted (v1.18 R1 forbids the fold).
