Module extended_int 

Extended integer type support: i128 and u128.

NumPy does not expose native int128 / uint128 dtypes, but PyO3 can round-trip Rust i128 / u128 values through Python’s arbitrary-precision int type. This module provides:

• Free functions to_i128, from_i128, to_u128, from_u128 for single-value conversion.
• I128Array and U128Array — Python-visible fixed-size containers backed by Vec<i128> / Vec<u128> respectively.

Structs

I128Array

A Python-visible fixed-size array of i128 values.

U128Array

A Python-visible fixed-size array of u128 values.

Functions

from_i128

Convert a Rust i128 to a Python int.

from_u128

Convert a Rust u128 to a Python int.

register_extended_int_module

Register extended-integer types and conversion functions into a PyO3 module.

to_i128

Convert a Python int to a Rust i128.

to_u128

Convert a Python int to a Rust u128.
