Struct IoTargetBusy 

pub struct IoTargetBusy<V>
where
    V: Identities,
{
    pub target: IoTargetKey,
    pub in_flight: usize,
    pub held_for_gate: usize,
    pub lowest_gates: Vec<Epoch<V>>,
    pub uncovered: usize,
    pub uncovered_through: Vec<Epoch<V>>,
    pub failures: Vec<<V as Identities>::FailureId>,
}

Everything still holding a file that remove_target refused, and what clears each hold. Every field is reported, not only the first that applies, so one refusal says all a consumer has to do.

Fields

target: IoTargetKey

The target.

in_flight: usize

Operations the kernel has not completed. Cleared as their completions arrive, which may be before they are popped (DI-D-45).

held_for_gate: usize

Operations held until their gate epoch is durable. Cleared when the gates are released, or fail as NeverIssued.

lowest_gates: Vec<Epoch<V>>

The lowest gate in each lineage gated on.

uncovered: usize

Writes to the file not yet covered successfully – named to a provider that answered success for every domain of the file – outside any failure’s suspect set. A file stays busy while any lineage has such a write. Cleared by make_durable_through at or above each.

uncovered_through: Vec<Epoch<V>>

The highest epoch among the uncovered writes, in each lineage that wrote the file.

failures: Vec<<V as Identities>::FailureId>

Unresolved failures whose suspect sets include writes to the file. Cleared by resolving them: heal and seal again, or abandon.
