Crate rustler_bigint

Github

BigInt is a helper type to support using large integers in Rust nifs

BigInt type is a wrapper around num-bigint this crate is also exposed via rustler_bigint::num_bigint

Example

use rustler::{NifResult, Error};
use rustler_bigint::BigInt;

#[rustler::nif]
pub fn add(left: BigInt, right: BigInt) -> NifResult<BigInt> {
    // BigInt implements deref so we can just use num-bigint methods directly
    if let Some(result) = left.checked_add(&right) {
        Ok(result.into())
    } else {
        Err(Error::RaiseAtom("number_overflow"))
    }
}
