The global context for Python compilation.

Fields

python_namespace: String

Python imports are mapped into a given namespace that can be changed.

python_path: Vec<String>

The default path we will search for Python modules.

imports: BTreeMap<String, HashSet<String>>

Collects all of the things we need to compile imports[module][asnames]

stdpython: String

with_std_python: bool

allow_unsafe: bool

async_runtime: AsyncRuntime

The async runtime to use for async Python code

lossy_warnings: bool

Emit #[deprecated] notes on generated items whose conversion was lossy (dropped parameter defaults, ignored return annotations, …). On by default: silent semantic divergence from the Python source is exactly what these warnings exist to surface. Tools may disable this to suppress the warnings at the user’s explicit request.

optional_names: Rc<HashSet<String>>

Names in the CURRENT scope that hold an Option (assigned None on some path, or annotated Optional): non-None stores into them wrap in Some. Set per scope by the function/module generators.

clone_str_attribute_returns: bool

Whether the CURRENT function’s return annotation is str: returning an attribute chain then clones the String field out of the shared receiver. Python strings are immutable, so the clone reproduces Python’s aliasing semantics exactly. Set per function.

local_types: Rc<HashMap<String, String>>

Statically-known types of names in the CURRENT scope (parameter annotations and literal assignments), as canonical Python type names (“int”, “float”, “str”, “bool”). Set per function; consumed by isinstance(), which lowers to a constant.

no_std: bool

Target stdpython’s no_std (alloc) tier. Python constructs that need the OS — print/input/open, imports of os/datetime/random/…, and __main__ entry points — fail loudly at conversion time instead of surfacing as resolution errors when the generated crate builds.
