brik64-bir

Embeddable BRIK-64 BIR bytecode runtime for Rust.

BIR (BRIK Intermediate Representation) is the portable bytecode format produced by the brikc compiler. This crate lets you load and execute BIR programs from any Rust project — no compiler toolchain required at runtime.

Installation

[dependencies]
brik64-bir = "2.0"

Usage

use brik64_bir::{BirModule, BirInterpreter};

let bir_source = std::fs::read_to_string("program.bir").unwrap();
let module = BirModule::parse(&bir_source).unwrap();
let mut interp = BirInterpreter::new(module);
let result = interp.run("fn::main", &[]).unwrap();
println!("Result: {}", result);

BIR Format

BIR is a human-readable line-based bytecode:

FUNCTION fn::add [$a $b] -> i64
  LOAD $x $a
  LOAD $y $b
  CALL_MC 0          ; MC_00 ADD8
  STORE $result $r0
  RETURN $result
END
