luaur-web 0.1.3

WebAssembly bindings to run and type-check Luau in the browser (Rust).
Documentation
//! Port of `DemoConfigResolver : Luau::ConfigResolver` (`CLI/src/Web.cpp:49-62`).
//!
//! The luau.org/demo config resolver. Defaults to `Mode::Nonstrict` so each
//! script's own mode comment governs (a deliberate playground deviation from
//! `Web.cpp`'s hard `Strict`; see `methods/demo_config_resolver_demo_config_resolver`).
//! Like the
//! analysis `ConfigResolver` (a struct with a fn-pointer vtable slot for the
//! single pure virtual `getConfig`), this concrete subclass is `#[repr(C)]` with
//! `base: ConfigResolver` first so a `*const ConfigResolver` (the vtable
//! receiver) can be cast back to `*const DemoConfigResolver` to reach
//! `default_config`.
//!
//! C++ member: `Luau::Config defaultConfig;`.
