aion-nif

Native function declaration helpers for Gleam and Elixir Aion workflows. The crate provides typed conversions between BEAM terms and Aion payloads, deterministic and activity NIF descriptors, registry builders, and suspension helpers used by workflow runtimes.

Install

[dependencies]
aion-nif = "0.1.0"

Key public types

  • Nif, Determinism, NifSet, and NifSetBuilder describe and collect native functions.
  • NifContext wraps the BEAM process context used during conversions.
  • FromTerm, IntoTerm, AtomName, and payload helpers bridge typed Rust values and BEAM terms.
  • deterministic_nif!, activity_nif!, and ActivityWakeHandle support declaration and suspension.
  • NifDeclError and TermError report declaration and conversion failures.

Minimal usage

use aion_nif::{NifSet, deterministic_nif};

fn double(value: i64) -> i64 {
    value * 2
}

let nifs = NifSet::builder()
    .register(deterministic_nif!("math", "double", double, (value: i64) -> i64))?
    .build();
assert_eq!(nifs.len(), 1);
