The "base64url" encoding. Pad characters are recommended (use ~np when including in a URL, because pads must be percent-encoded). Non-alphabet characters are forbidden.
val basis : Cf_radix_n.basisThe basis of the transform.
Use decode_seq s to decode the digits in s according to the rules for the transform. Evaluating the result raises Error if an error in the encoding is encountered. Optionally use ~n to specify the required length of the decoded octets, raising Error if the end of s is not found immediately following the last digit in the encoding.
Use decode_string s to decode the digits in s according to the rules for the transform. Returns None if an error is encountered. Optionally use ~n to specify the required length of the decoded octets.
val decode_slice : ?n:int -> string Cf_slice.t -> string optionUse decode_slice s to decode the digits in s according to the rules for the transform. Returns None if an error is encountered. Optionally use ~n to specify the required length of the decoded octets.
Use encode_seq s to encode the octets in s according to the rules for the transform. Use ~brk:(n, s) to insert s every n digits. Use ~np:() to disable output of pad characters. If pad characters are mandatory for the transform, then using ~np:() raises Invalid_argument.
Use encode_string s to encode the octets in s according to the rules for the transform. Use ~brk:(bn, bs) to insert bs every bn digits. Use ~np:() to disable output of pad characters. If pad characters are mandatory for the transform, then using ~np:() raises Invalid_argument.
