  2. Docs

Module contains helper function for serializing and deserializing tuples, records and variants. Deserialization functions may raise Helper.Protocol exception. It is recommended that the calling functions convert this exception into a Driver.Protocol_exception

exception Protocol_error of Base.string

Excpetion raised if the type could not be serialized

val map_record_in : 't 'a 'b. (Base.string -> Base.string) -> ('t, 'a, 'b) Record_in.t -> ('t, 'a, 'b) Record_in.t

Map fields names of a Record_in structure

val to_record : 't 'constr 'b. ?strict:Base.bool -> ('t, 'constr, 'b) Record_in.t -> 'constr -> (Base.string * 't) Base.list -> 'b

to_recordspecconstructorts returns the constructed value. ts is a associative array (string * t) list, mapping fields to the deserialized value t if strict is true, an error will be raised if input contains an unknown field. If dublicate fields are found in the input, an error is raised

val map_record_out : 't 'a. (Base.string -> Base.string) -> ('t, 'a, 't) Record_out.t -> ('t, 'a, 't) Record_out.t

Map fields names of a Record_out structure

type 't serialize_record = (Base.string * 't) Base.list -> 't
val of_record : 't 'a. omit_default:Base.bool -> 't serialize_record -> ('t, 'a, 't) Record_out.t -> 'a

of_recordmap_fspec produces a valid deserialisation function for a record type The map_f function is called to produce the serialized result from a field_name, t association list. If omit_default is true, then default values are omitted from the output

val to_tuple : 't 'a 'b. ('t, 'a, 'b) Tuple_in.t -> 'a -> 't Base.list -> 'b

to_tuplespectlist produces a tuple from the serialized values in tlist

type 't serialize_tuple = 't Base.list -> 't
val of_tuple : 't 'a. 't serialize_tuple -> ('t, 'a, 't) Tuple_out.t -> 'a
type 't serialize_variant = Base.string -> 't Base.list -> 't
val of_variant : 't. 't serialize_variant -> Base.string -> ('t, 'a, 't) Tuple_out.t -> 'a

of_variantspecv serializes v and returns the serialized values as a list or map

val map_constructor_names : (Base.string -> Base.string) -> ('t, 'a) Variant_in.t Base.list -> ('t, 'a) Variant_in.t Base.list

Map field names in all inline records of the spec

val to_variant : ('t, 'a) Variant_in.t Base.list -> Base.string -> 't Base.list -> 'a
