Struct ExecState 

pub struct ExecState<P: ProcessManager> { /* private fields */ }

Execution state for one script run. Public so hosts can register functions and introspect listings; all fields stay crate-private so the scope, recursion-budget, and task invariants cannot be broken from outside.

Implementations

impl<P: ProcessManager> ExecState<P>

pub fn register_module(&mut self, module: HostModule<P>)

Register one HostModule: every function becomes callable as MODULE::NAME, every type joins the run’s name directory.

pub fn list_functions(&self) -> Vec<FuncMeta>

All visible functions: natives plus hosts plus current DSL definitions.

pub fn describe_function(&self, name: &str) -> Option<Value>

Describe one function by name, or None when unknown.

impl<P: ProcessManager> ExecState<P>

pub fn register_type(&mut self, descriptor: &'static TypeDescriptor)

Register a host-defined type descriptor (usually T::descriptor() for a #[oxdock_type] payload). Makes the name visible to TYPES() and valid for LET $x: NAME declarations carrying same-named payloads. Re-registering a name returns silently when the descriptor is identical; a different descriptor under a live name panics instead of aliasing two layouts.

pub fn is_known_type(&self, name: &str) -> bool

True when name names a registered type (startup or host).

pub fn describe_type(&self, name: &str) -> Option<&'static TypeDescriptor>

Resolve a descriptor by name, or None when unregistered.

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

Every registered type name: startup descriptors first, then hosts in registration order.
