Crate symbios 

Symbios

A Sovereign Derivation Engine for Parametric L-Systems.

Symbios is a pure-Rust engine for generating Lindenmayer Systems, strictly adhering to the syntax and semantics defined in The Algorithmic Beauty of Plants (Prusinkiewicz & Lindenmayer, 1990).

It is designed for high-performance, embedded, and WebAssembly environments where reliability and determinism are paramount.

Key Features

• Sovereign Architecture: Zero heavy dependencies.
• Structure-of-Arrays (SoA): Optimized memory layout for cache locality.
• Parametric: Full support for arithmetic expressions in rules.
• Context-Sensitive: (k,l)-systems with variable binding.

Example

use symbios::System;

let mut sys = System::new();
// Define a rule: A module 'A' grows if parameter 'x' is small
sys.add_rule("A(x) : x < 10 -> A(x + 1) B(x)").unwrap();
sys.set_axiom("A(0)").unwrap();
sys.derive(5).unwrap();
