Struct SweepOutcome 

pub struct SweepOutcome {
    pub moved: usize,
    pub unkeyable: usize,
    pub rows: usize,
}

What a sweep of dynamic_workers accounted for. The retired table is only safe to drop when Self::drained, and everything else holds it for a later boot.

Fields

moved: usize

Rows copied into sessions and removed from the retired table.

unkeyable: usize

Rows left where they are: no configured project carries their key, so they cannot be keyed by (org, project, label).

rows: usize

Rows the retired table held when the sweep looked.

Implementations

impl SweepOutcome

pub fn drained(&self) -> bool

Nothing is left in the retired table: every row it held was copied, so dropping it loses nothing. An unkeyable row counts as not drained by construction - it is in rows and not in moved - and a later boot retries it, which is what the hold is for.
