matter#

Matter protocol implementation for OCaml.

Overview#

This library provides an implementation of the Matter smart home protocol as specified in the Matter Core Specification.

Features#

• TLV (Tag-Length-Value) encoding and decoding
• Support for all Matter TLV types: integers, booleans, floats, strings, bytes, null
• Nested containers: structures, arrays, lists
• All tag forms: anonymous, context-specific, common/implicit profile, fully-qualified

Installation#

opam install matter

Usage#

open Matter.Tlv

(* Create elements *)
let elem = structure [
  ctx_int 1 42;
  ctx_string 2 "hello";
  ctx_bool 3 true;
]

(* Encode to binary *)
let binary = encode_one elem

(* Decode from binary *)
match decode binary with
| Ok elements -> (* process elements *)
| Error msg -> (* handle error *)

API#

TLV Module#

• Matter.Tlv.encode - Encode elements to binary TLV
• Matter.Tlv.decode - Decode binary TLV to elements
• Matter.Tlv.int, uint, bool, string, bytes, null - Value constructors
• Matter.Tlv.structure, array, list - Container constructors
• Matter.Tlv.ctx_int, ctx_uint, etc. - Context-tagged constructors
