Turn Off Script Optimizations

{{#include ../../links.md}}

When scripts:

• are known to be run only once and then thrown away,

• are known to contain no dead code,

• do not use constants in calculations

the optimization pass may be a waste of time and resources.

In that case, turn optimization off by setting the optimization level to [OptimizationLevel::None].

let engine = rhai::Engine::new();

// Turn off the optimizer
engine.set_optimization_level(rhai::OptimizationLevel::None);

Alternatively, disable optimizations via the [no_optimize] feature.
