Grift Standard Library

Standard library features for the Grift R7RS-compliant Scheme implementation that require Rust's std (I/O, filesystem, etc.).

This crate implements the [IoProvider] trait from grift_core using Rust's standard I/O, giving the no_std evaluator access to real input/output when running on a hosted platform.

Quick Start

use grift_std::StdIoProvider;
use grift_core::IoProvider;

// Create a standard I/O provider
let mut io = StdIoProvider::new();

// Check port types
use grift_core::PortId;
assert!(io.is_input_port(PortId::STDIN));
assert!(io.is_output_port(PortId::STDOUT));
