Struct ToolRegistry 

pub struct ToolRegistry { /* private fields */ }

An ordered set of tools offered to the model.

Implementations

impl ToolRegistry

pub fn new() -> ToolRegistry

An empty registry.

pub fn with_builtins() -> ToolRegistry

A registry pre-populated with all built-in tools.

pub fn from_config(config: &Config) -> ToolRegistry

P3 (COMPOSABLE-HARNESS-DESIGN.md §5.2 phase P3): build a registry from a resolved Config’s module-activation set, the intended replacement for unconditional Self::with_builtins call sites.

Mandatory risk-2 mitigation (§5.3 risk 2 — “land P3 behind [experimental] module_registry = true”): when Config::module_registry is false (the default), this returns EXACTLY Self::with_builtins — same 10 tools, same order, zero behavior change. Only when the flag is explicitly on does Config::module_activation/Config::core_tools_enabled start shaping which tool objects get registered AT ALL: a disabled module contributes no tool (never registered, so never advertised and never mentioned anywhere) — e.g. todos off means update_plan is not in this registry; tools_search off (or its list_dir/glob/ content_search sub-flags off) means the corresponding tool is absent too.

pub fn register(&mut self, tool: impl Tool + 'static)

Add a tool. A later registration with the same name shadows the earlier.

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

Look up a tool by name (last registration wins).

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

Iterate all tools.

pub fn len(&self) -> usize

Number of registered tools.

pub fn is_empty(&self) -> bool

Whether the registry is empty.

Trait Implementations

impl Default for ToolRegistry

fn default() -> ToolRegistry

Returns the “default value” for a type.
