bridge.utils.instantiate_utils._DISALLOWED_CALLABLE_FIELD_NAMES: set[str]#: None

bridge.utils.instantiate_utils._as_module_prefix(prefix: str) → str#: Ensure prefix ends with ‘.’ so allowlist matches at module boundaries.

bridge.utils.instantiate_utils._seed_allowlist() → None#

bridge.utils.instantiate_utils.register_allowed_target_prefix(prefix: str) → None#

Register an additional allowed module prefix for target instantiation.

This allows extending the default allowlist for use cases that require instantiating classes from other packages.

bridge.utils.instantiate_utils._reject_unsafe_target_name( *, target: str, full_key: str | int, ) → None#: Reject known unsafe target names without importing their modules.

bridge.utils.instantiate_utils._validate_target_prefix(*, target: str, full_key: str | int) → None#: Validate that a target string is permitted by Bridge hardening rules.

bridge.utils.instantiate_utils._resolve_target( target: str | type | Callable[..., Any], full_key: str | int, check_callable: bool = True, ) → type | Callable[..., Any] | object#: Resolve target string, type, or callable after Bridge validation.
