Module
Module type
Parameter
Class
Class type

An abstraction on top of the index library that exposes an API that better fits the irmin-pack use case.

Parameters

module K : Irmin.Hash.S

Signature

type t
type key = K.t
type value = Optint.Int63.t * int * Irmin_pack.Pack_value.Kind.t
include Index.S with type value := value and type t := t and type key := key
type cache

The type for caches of index instances.

val empty_cache : unit -> cache

Construct a new empty cache of index instances.

val clear : t -> unit

clear t clears t so that there are no more bindings in it.

val replace : ?overcommit:bool -> t -> key -> value -> unit

replace t k v binds k to v in t, replacing any existing binding of k.

If overcommit is true, the operation does not triger a merge, even if the caches are full. By default overcommit is false.

val sync : t -> unit

sync t syncs a read-only index with the files on disk. Raises RW_not_allowed if called by a read-write index.

val is_merging : t -> bool

is_merging t returns true if t is running a merge. Raises RO_not_allowed if called by a read-only index.

module Checks : sig ... end

Offline fsck-like utility for checking the integrity of Index stores built using this module.
