Data_encoding.Variable
Create encodings that produce data of a variable length when binary encoded. See the preamble for an explanation.
val string : string encoding
val bytes : bytes encoding
val array : ?max_length:int -> 'a encoding -> 'a array encoding
if the encoding argument is variable length or may lead to zero-width representation in binary.
val list : ?max_length:int -> 'a encoding -> 'a list encoding
