Signal end-of-stream by pushing a sentinel None.

Called by the client receive loop to push items.

Deliver a response to a single map entry and return whether the delivery happened.

Open a handle (stream/channel), send the envelope, and register cleanup.

Convert a type string (or already-shaped descriptor) to a structural descriptor.

Fire-and-forget invocation. No response is expected.

* Fire-and-forget invocation. No response is expected.

Open a bidirectional channel and return a SaikuroChannel.

Open a bidirectional channel. Use the returned [`SaikuroChannel`] to send and receive values.

A convenience wrapper that checks against a resolved [`FunctionRef`].

* Decorator-style registration. Returns a function that registers the * decorated handler and then returns it unchanged. * * Usage: * @

Remove all namespace registrations for the given provider ID.

Deregister a provider by ID (called on disconnect).

Dispatch an invocation directly (bypassing transport encoding). Used by in-process providers and the test harness. Validation and capability-checking

Dispatch a `Cast` envelope. Runs the handler but never sends a response.

Map this error to the appropriate wire [`ErrorCode`].

Load *source_path* as a Python module and build a Saikuro schema dict.

Look up a namespace, returns an error if it doesn't exist.

Return `true` if this set grants the given capability. The wildcard token `"*"` grants every capability.

Map a `saikuro::Result<()>` to a C `c_int` return, setting `last_error` on failure.

Safety: The `user_data` pointer is captured and later used inside asynchronous callbacks registered with the provider. Callers must ensure that the `u

Forward a structured log record to the runtime log sink. Fire-and-forget; no response is expected.

Look up the schema for a single function. `target` must be in `"namespace.function"` format.

Create a JS object literal from key-value pairs.

Create a new runtime builder for the wasm backend.

Wrap this descriptor in `Option`.

Build an `IDBKeyRange` covering all keys beginning with `prefix`.

Process one character. Returns true if `c` is `delimiter` at top level and outside any quotes. When `is_angle_operator` is true, `<`/`>` are treated a
