vowpalwabbit-sys-8.8.1+vw-v8.8.0
Rust bindings for the VowpalWabbit C-binding surface.
Note: Currently this crate only supports discovering VW through pkg-config
, therefore VowpalWabbit
must be installed using make install
for this crate to be able to find it and link to it. This
crate is not yet supported on Windows, once VW supports Vcpkg then this crate will use that to discover it.
In order to get the library installed:
- Clone VowpalWabbit
mkdir build
cd build
make -j 8
make install
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);
