fast-yaml-ffi

FFI utilities for fast-yaml language bindings.

Installation

Add to your Cargo.toml:

[dependencies]
fast-yaml-ffi = "0.3"

Or with cargo-add:

cargo add fast-yaml-ffi

[!IMPORTANT] Requires Rust 1.88 or later.

Overview

This crate provides generic traits and utilities for converting between Rust types and foreign types (Python via PyO3, Node.js via NAPI-RS).

Core Traits

• ToFfi<T> — Convert Rust types to foreign types
• FromFfi<T> — Convert foreign types to Rust types

Usage

use fast_yaml_ffi::{ToFfi, FromFfi};

// Convert Rust value to Python object
let py_obj = rust_value.to_ffi()?;

// Convert Python object to Rust value
let rust_value = RustType::from_ffi(&py_obj)?;

[!NOTE] This crate is primarily used internally by fast-yaml (Python) and fast-yaml-nodejs bindings.
