Struct ToolIndex 

pub struct ToolIndex { /* private fields */ }

One-time index built from the global inventory at startup. Holds definitions in registration order (so tools/list output is deterministic across builds — inventory::iter itself orders entries by submission link order, but we sort by name to remove that dependency for tests) and a name → dispatch map for tools/call.

Implementations

impl ToolIndex

pub fn from_inventory() -> Self

Build the index from inventory::iter::<McpToolEntry>().

FALSIFY-INVENTORY-002: panics with a clear diagnostic if two entries share the same name. The panic fires the first time any test or production path constructs an AprMcpServer, so a duplicate-name regression cannot escape CI.

pub fn definitions(&self) -> &[ToolDefinition]

All tool definitions advertised by tools/list, sorted by name.

pub fn dispatch_for(&self, name: &str) -> Option<&DispatchFn>

Look up the dispatch function for a tools/call request. Returns None if no tool with that name is registered — the caller is responsible for emitting the appropriate isError envelope.

pub fn names(&self) -> Vec<&'static str>

Names of all registered tools, alphabetically sorted. Used by FALSIFY-INVENTORY-001 to assert the migrated set matches the pre-migration golden list.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
