API reference

The Python API is the recommended high-level interface for NumPy workflows. Its pages are generated by mkdocstrings from the installed fpm_rs package, its .pyi type surface, and public docstrings; signatures are not copied manually into Markdown.

The Rust API is generated by native rustdoc for the public fpm-rs crate. Use it for lower-level integrations, algorithm development, lazy measurements, custom callbacks, and performance-sensitive code.

Both surfaces document the single API intended for the first public release.
