Fields

module_name: Option<String>

async_runtime: Option<String>

stubs: Option<StubsConfig>

pip_name: Option<String>

PyPI package name (e.g. "html-to-markdown"). Used as the [project] name in pyproject.toml and to derive the python-packages list for maturin. Defaults to the crate name.

features: Option<Vec<String>>

Per-language feature override. When set, these features are used instead of [crate] features for this language’s binding crate.

serde_rename_all: Option<String>

Override the serde rename_all strategy for JSON field names (e.g. “camelCase”, “snake_case”). When set, this takes priority over the IR type-level serde_rename_all.

capsule_types: HashMap<String, String>

Map of type name -> PyCapsule name for raw pointer wrapping. When a function returns one of these types, alef generates PyCapsule_New instead of Arc wrapping.

release_gil: bool

When true, wrap blocking function bodies in py.allow_threads() to release the GIL.

exclude_functions: Vec<String>

Functions to exclude from Python binding generation.

exclude_types: Vec<String>

Types to exclude from Python binding generation.

extra_dependencies: HashMap<String, Value>

Additional Cargo dependencies for this language’s binding crate only.

scaffold_output: Option<PathBuf>

Override the scaffold output directory for this language’s Cargo.toml and package files.

rename_fields: HashMap<String, String>

Per-field name remapping for this language. Key is TypeName.field_name (e.g. "LayoutDetection.class"), value is the desired binding field name. Applied after automatic keyword escaping, so an explicit entry takes priority.

run_wrapper: Option<String>

Prefix wrapper for default tool invocations. When set, prepends this string to default commands across all pipelines (lint, test, build, etc.). E.g., run_wrapper = "uv run --no-sync" turns ruff format packages/python into uv run --no-sync ruff format packages/python.

extra_lint_paths: Vec<String>

Extra paths to append to default lint commands (format, check, typecheck). Space-separated paths are appended to the command.
