Enum GcArm 

pub enum GcArm {
    NewGeneration,
    CompactInPlace,
}

Which Gc GitOps::gc runs as its third step, after reachability and after the dead index rows are dropped.

Variants

NewGeneration

NewGeneration — the default. Hard-link, compact the link, verify the result by reading every entry back, rename to x.gN.znippy, unlink the old generation last. A death at any point leaves at least one complete readable archive.

CompactInPlace

CompactInPlace — base znippy’s compact_archive against the archive under its own name: stage beside it, rename over it. Verification is post-hoc: by the time there is something to read back, the original is already gone. One archive on disk instead of two, and no generation suffix — which is the reason to pick it — at the price of that window.

Implementations

impl GcArm

pub const ALL: [GcArm; 2]

pub fn as_str(self) -> &'static str

pub fn strategy(self) -> &'static str

The name the built implementation reports through Gc::name, which is also what lands in GcReport::strategy — the applied output a guard reads.

pub fn create(self) -> Box<dyn Gc + Send + Sync>

Build it. Send + Sync because a GitStore is shared across the indexer’s threads.

pub fn parse(s: &str) -> Result<Self>
