val get_all_accounts_rooted_at_exn : 
  t ->
  Addr.t ->
  (Addr.t * Mina_base.Account.t) list

Get all of the accounts that are in a subtree of the underlying Merkle tree rooted at `address`. The accounts are ordered by their addresses.

val make_space_for : t -> int -> unit

val to_list : t -> Mina_base.Account.t list

list of accounts in the ledger

val iteri : t -> f:( index -> Mina_base.Account.t -> unit ) -> unit

iterate over all indexes and accounts

val foldi : 
  t ->
  init:'accum ->
  f:( Addr.t -> 'accum -> Mina_base.Account.t -> 'accum ) ->
  'accum

fold over accounts in the ledger, passing the Merkle address

  t ->
  Mina_base.Account_id.Set.t ->
  init:'accum ->
  f:( Addr.t -> 'accum -> Mina_base.Account.t -> 'accum ) ->

the set of account_ids are ledger elements to skip during the fold, because they're in a mask

  f:
    ( 'accum ->
      Mina_base.Account.t ->
      ( 'accum, 'stop ) Base.Continue_or_stop.t ) ->
  finish:( 'accum -> 'stop ) ->
  'stop

fold over accounts until stop condition reached when calling f; calls finish for result

val accounts : t -> Mina_base.Account_id.Set.t

set of account ids associated with accounts

val token_owner : t -> Mina_base.Token_id.t -> Mina_base.Account_id.t option

Get the account id that owns a token.

val token_owners : t -> Mina_base.Account_id.Set.t

Get the set of all accounts which own a token.

val tokens : 
  t ->
  Signature_lib.Public_key.Compressed.t ->
  Mina_base.Token_id.Set.t

Get all of the tokens for which a public key has accounts.

val get_or_create_account : 
  t ->
  Mina_base.Account_id.t ->
  Mina_base.Account.t ->
  ([ `Added | `Existed ] * Location.t) Core.Or_error.t

This may return an error if the ledger is full.

val close : t -> unit

the ledger should not be used after calling close

val last_filled : t -> Location.t option

for account locations in the ledger, the last (rightmost) filled location

val get_uuid : t -> Uuid.t

val get_directory : t -> string option

return Some directory for ledgers that use a file system, else None

val get : t -> Location.t -> Mina_base.Account.t option

val get_batch :

  Location.t list ->
  (Location.t * Mina_base.Account.t option) list

val merkle_root : t -> Mina_base.Ledger_hash.t

meant to be a fast operation: the root hash is stored, rather than calculated dynamically

val merkle_path_at_index_exn : t -> int -> Path.t

val remove_accounts_exn : t -> Mina_base.Account_id.t list -> unit

val detached_signal : t -> unit Async_kernel.Deferred.t

Triggers when the ledger has been detached and should no longer be accessed.

exception Dangling_parent_reference of Uuid.t * string

val get_hash : t -> Addr.t -> Mina_base.Ledger_hash.t option

get hash from mask, if present, else from its parent

val commit : t -> unit

commit all state to the parent, flush state locally

val unset_parent : ?trigger_signal:bool -> loc:string -> t -> unattached

unset_parent ?trigger_signal ~loc:__LOC__ t detaches the parent from t. The loc argument is shown in the Dangling_parent_reference exception, which will be raised if t is used while no parent is registered.

If the trigger_signal optional argument is true or omitted, detached_signal for t will be resolved. This should only be set to false when the mask will be reparented.

val get_parent : t -> Any_ledger.M.t

get mask parent

val parent_set_notify : t -> Mina_base.Account.t -> unit

called when parent sets an account; update local state

val copy : t -> t
