Crate vowpalwabbit_sys

Expand description

Rust bindings for the VowpalWabbit C-binding surface.

§Example

The following is an example for a basic usecase similar to command line driver mode. VW is initialized, an example run through the parser then prediction pipeline. Finally the example and VW object are finished.

use std::ffi::CString;

unsafe {
  let command_line_str = CString::new("--quiet").unwrap();
  let vw_handle = vowpalwabbit_sys::VW_InitializeA(command_line_str.as_ptr());
  let example_str =
    CString::new("1 | test example=1").unwrap();
  let example_handle = vowpalwabbit_sys::VW_ReadExampleA(vw_handle, example_str.as_ptr());

  vowpalwabbit_sys::VW_Predict(vw_handle, example_handle);
  vowpalwabbit_sys::VW_Learn(vw_handle, example_handle);
  vowpalwabbit_sys::VW_FinishExample(vw_handle, example_handle);
  vowpalwabbit_sys::VW_Finish(vw_handle);
}
