Rust Bindings for Grok

FFI bindings generated with bindgen. The crate wraps the libgrokj2k C API and provides raw unsafe access to all public functions and types.

Prerequisites

• Rust toolchain (stable)
• pkg-config
• Grok installed (so that pkg-config --libs libgrokj2k works)

If Grok is installed to a non-standard prefix:

# Linux
export PKG_CONFIG_PATH=/path/to/grok/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/path/to/grok/lib:$LD_LIBRARY_PATH

# macOS
export PKG_CONFIG_PATH=/path/to/grok/lib/pkgconfig:$PKG_CONFIG_PATH
export DYLD_LIBRARY_PATH=/path/to/grok/lib:$DYLD_LIBRARY_PATH

Windows: The build script currently requires pkg-config. On Windows you can use pkg-config-lite or vcpkg to provide it, with PKG_CONFIG_PATH pointing to your Grok install.

Build

cargo build

Run Tests

cargo test --lib --tests

Run Example

cargo run --example initialize_grok

Usage

Add the crate as a dependency (local path or publish to a registry):

use grokj2k_sys::*;
use std::ffi::CStr;

fn main() {
    unsafe {
        grk_initialize(std::ptr::null(), 0, std::ptr::null_mut());
        let version = CStr::from_ptr(grk_version());
        println!("Grok version: {}", version.to_str().unwrap());
        grk_deinitialize();
    }
}
