Detailed Description

Simple C-contiguous buffer descriptor for Python interop.

Compatible with Python's buffer protocol (PEP 3118) and pybind11's py::buffer_info. Can also be used to construct NumPy's __array_interface__ dict.

Format strings follow Python struct module conventions: "f" = float32, "d" = float64, "i" = int32, "l" = int64, "b" = int8, "B" = uint8, "h" = int16, "e" = float16, "?" = bool

Note: Strides are always in bytes (not elements), matching PEP 3118.
