Node is the underlying node store.
Content-addressable stores are store where it is possible to read and add new values. Keys are derived from the values raw contents and hence are deterministic.
The type for content-addressable backend stores. The 'a phantom type carries information about the store mutability.
type key = Val.hashThe type for keys.
val mem : [> Irmin.Perms.read ] t -> key -> bool Lwt.tmem t k is true iff k is present in t.
val find : [> Irmin.Perms.read ] t -> key -> value option Lwt.tfind t k is Some v if k is associated to v in t and None is k is not present in t.
val add : [> Irmin.Perms.write ] t -> value -> key Lwt.tWrite the contents of a value to the store. It's the responsibility of the content-addressable store to generate a consistent key.
val unsafe_add : [> Irmin.Perms.write ] t -> key -> value -> unit Lwt.tSame as add but allows to specify the key directly. The backend might choose to discared that key and/or can be corrupt if the key scheme is not consistent.
module Path : Irmin.Path.SPath provides base functions on node paths.
val merge : [> Irmin.Perms.read_write ] t -> key option Irmin.Merge.tmerge is the 3-way merge function for nodes keys.
Key provides base functions for node keys.
module Metadata : sig ... endMetadata provides base functions for node metadata.
module Val : sig ... endVal provides base functions for node values.
module Contents : Irmin.Contents.STORE with type key = Val.hashContents is the underlying contents store.
