type 'data t
val empty : 'data t

The empty dictionary.

val singleton : key -> 'data -> 'data t

Dictionary with a single key/value pair.

val of_alist : (key * 'data) list -> [ `Ok of 'data t | `Duplicate_key of key ]

Dictionary containing the given key/value pairs. Fails if there are duplicate keys.

val of_alist_or_error : (key * 'data) list -> 'data t Or_error.t

Like of_alist. Returns a Result.t.

val of_alist_exn : (key * 'data) list -> 'data t

Like of_alist. Raises on duplicates.

val of_alist_multi : (key * 'data) list -> 'data list t

Produces a dictionary mapping each key to a list of associated values.

val of_alist_fold : (key * 'data) list -> init:'acc -> f:('acc -> 'data -> 'acc) -> 'acc t

Produces a dictionary using each key/value pair. Combines all values for a given key with init using f.

val of_alist_reduce : (key * 'data) list -> f:('data -> 'data -> 'data) -> 'data t

Produces a dictionary using each key/value pair. Combines multiple values for a given key using f.

val of_sequence : (key * 'data) Sequence.t -> [ `Ok of 'data t | `Duplicate_key of key ]

Like of_alist. Consumes a sequence.

val of_sequence_or_error : (key * 'data) Sequence.t -> 'data t Or_error.t

Like of_alist_or_error. Consumes a sequence.

val of_sequence_exn : (key * 'data) Sequence.t -> 'data t

Like of_alist_exn. Consumes a sequence.

val of_sequence_multi : (key * 'data) Sequence.t -> 'data list t

Like of_alist_multi. Consumes a sequence.

val of_sequence_fold : (key * 'data) Sequence.t -> init:'c -> f:('c -> 'data -> 'c) -> 'c t

Like of_alist_fold. Consumes a sequence.

val of_sequence_reduce : (key * 'data) Sequence.t -> f:('data -> 'data -> 'data) -> 'data t

Like of_alist_reduce. Consumes a sequence.

val of_list_with_key : 'data list -> get_key:('data -> key) -> [ `Ok of 'data t | `Duplicate_key of key ]

Like of_alist. Consume values for which keys can be computed.

val of_list_with_key_or_error : 'data list -> get_key:('data -> key) -> 'data t Or_error.t

Like of_alist_or_error. Consume values for which keys can be computed.

val of_list_with_key_exn : 'data list -> get_key:('data -> key) -> 'data t

Like of_alist_exn. Consume values for which keys can be computed.

val of_list_with_key_multi : 'data list -> get_key:('data -> key) -> 'data list t

Like of_alist_multi. Consume values for which keys can be computed.

val of_iteri : iteri:(f:(key:key -> data:'data -> unit) -> unit) -> [ `Ok of 'data t | `Duplicate_key of key ]

Produces a dictionary of all key/value pairs that iteri passes to ~f. Fails if a duplicate key is found.

val of_iteri_exn : iteri:(f:(key:key -> data:'data -> unit) -> unit) -> 'data t

Like of_iteri. Raises on duplicate key.
