Struct FunctionRegistry 

pub struct FunctionRegistry { /* private fields */ }

All loaded functions, keyed by manifest name.

Implementations

impl FunctionRegistry

pub fn load(app: &App) -> Self

The registry an app runs with: the framework’s built-ins first, then everything in the app’s functions/ directory.

Built-ins live in the reserved apiplant_ namespace, so an app function can’t shadow one by accident. Naming one into that namespace on purpose still replaces the built-in — the escape hatch for an app that wants the hook but not our version of it — and says so in the log.

pub fn register_builtin( &mut self, manifest: FunctionManifest, handler: BuiltinHandler, config_json: String, )

Add a built-in under its manifest name. See crate::builtins.

pub fn load_dir(dir: &Path) -> Self

Scan a directory for function libraries and load them all. Missing dir = empty registry. A single bad library is logged and skipped, never fatal.

pub fn register(&mut self, func: BoxedFunction, config_json: String)

Add a function that wasn’t loaded from disk, replacing any function of the same name. Lets a host embed functions directly.

pub fn get(&self, name: &str) -> Option<&LoadedFunction>

pub fn iter(&self) -> impl Iterator<Item = &LoadedFunction>

Trait Implementations
