Status codes

Overview

Fusion exposes HTTP status constants from fusion-core in every binding:

Language	Import
Python	`from fusion_framework import status` then `status.HTTP_SUCCESS`
TypeScript / Node	`import { status } from "fusion-framework"`
C#	`using FusionFramework;` then `Status.HTTP_SUCCESS`

HTTP_SUCCESS is an alias of HTTP_200_OK (200). Prefer these constants over raw integers.

return self.response({"ok": True}, status=status.HTTP_SUCCESS)

return this.response({ ok: true }, status.HTTP_SUCCESS);

return Response(new { ok = true }, Status.HTTP_SUCCESS);

Helpers (Rust / mirrored in bindings where exposed): is_informational, is_success, is_redirect, is_client_error, is_server_error.

Source of truth: crates/fusion-core/src/status.rs (HTTP_STATUS_CODES).
