Struct AdapterRegistry 

pub struct AdapterRegistry { /* private fields */ }

Registry that maps component IDs to their executor adapters.

The registry maintains two maps:

• Rust adapters: Components with native Rust implementations
• Legacy adapters: Components that fall back to shell scripts

When looking up a component, Rust adapters take priority. If no Rust adapter is registered, the legacy adapter is used. If neither exists, AdapterNotFound is returned.

Implementations

impl AdapterRegistry

pub fn new() -> Self

Create a new empty adapter registry.

pub fn with_legacy(scripts_dir: impl Into<PathBuf>) -> Self

Create a new adapter registry with the default legacy adapter.

The legacy adapter uses the scripts directory to find install_*.sh files. All 17 known components are registered for legacy fallback.

pub fn register_rust( &mut self, component_id: impl Into<String>, adapter: Box<dyn Adapter>, )

Register a Rust adapter for a component.

Rust adapters take priority over legacy adapters.

pub fn get_adapter( &self, component_id: &str, ) -> Result<AdapterRef, AdapterError>

Look up the adapter info for a component ID.

Returns an AdapterRef describing which executor would be used, without actually executing anything.

Priority:

1. Rust adapter (if registered)
2. Legacy adapter (if component has an installer script)
3. AdapterNotFound error

pub fn execute( &self, component_id: &str, version: &str, ) -> Result<AdapterOutput, AdapterError>

Execute a component via the appropriate adapter.

Routes to Rust adapter if registered, otherwise falls back to legacy.

pub fn has_rust_adapter(&self, component_id: &str) -> bool

Check if a component has a Rust adapter registered.

pub fn has_legacy_adapter(&self, component_id: &str) -> bool

Check if a component has a legacy adapter available.

pub fn executor_kind( &self, component_id: &str, ) -> Result<ExecutorKind, AdapterError>

Get the executor kind for a component.

pub fn rust_adapter_count(&self) -> usize

Get the number of registered Rust adapters.

pub fn legacy_adapter_count(&self) -> usize

Get the number of known legacy component IDs.

pub fn rust_component_ids(&self) -> Vec<String>

List all component IDs that have Rust adapters registered.

pub fn legacy_component_ids(&self) -> Vec<String>

List all component IDs that have legacy adapters available.

Trait Implementations

impl Default for AdapterRegistry

fn default() -> Self

Returns the “default value” for a type.
