Struct FsDiscoverer 

pub struct FsDiscoverer { /* private fields */ }

Filesystem-based module discoverer.

Recursively walks root looking for files named module.json, parses each one into a DiscoveredModule, and returns them all from discover().

Implementations

impl FsDiscoverer

pub fn new(root: impl Into<PathBuf>) -> Self

Create a new discoverer rooted at the given directory path.

pub fn get_executable(&self, module_name: &str) -> Option<PathBuf>

Return the resolved executable path for a module, if one was declared.

pub fn executables_snapshot(&self) -> HashMap<String, PathBuf>

Return a snapshot of all executable paths discovered so far.

pub fn load_descriptions(&self) -> HashMap<String, String>

Scan the extensions directory and return a map of module name to description.

This is a convenience method for populating description metadata that ModuleDescriptor does not carry. Non-parseable files are silently skipped.
