RuntimeRegistry

outl_exec::registry

Struct RuntimeRegistry 

Source 
pub struct RuntimeRegistry { /* private fields */ }
Expand description

Owned set of runtimes, keyed by the lowercased fence info-string.

Implementations§

Source§

impl RuntimeRegistry

Source

pub fn new() -> Self

Empty registry. Most callers want RuntimeRegistry::with_builtins.

Source

pub fn with_builtins() -> Self

New registry pre-populated with every shipped runtime.

Each language ships behind a feature (lang-lisp, lang-js, lang-python, lang-lua) so binaries can strip what they don’t need. echo is the smoke-test runtime — gated behind debug_assertions / test so release builds (notably the iOS IPA) don’t surface an “echo” language to the App Store reviewer; it has no production value and reads as a dev hook.

Source

pub fn register<R: Runtime + 'static>(&mut self, r: R) -> &mut Self

Insert (or replace) a runtime. The lookup key is the runtime’s own language(), lowercased.

Source

pub fn get(&self, lang: &str) -> Option<Arc<dyn Runtime>>

Look up a runtime by fence info-string. Returns None if no runtime is registered for that language.

The input is run through outl_md::lang::canonical first so user-written aliases (javascript, node, rs, py3, …) resolve to the registry key the runtime registered with (js, rust, python). The original lower-cased form is the fallback when no alias matches — keeps the door open for runtimes registered out-of-band that don’t have an alias entry yet.

Source

pub fn languages(&self) -> impl Iterator<Item = &str>

Every registered language. Useful for :run ? style help.
