Methods

impl<'a> Model<'a>

fn new(env: &'a Env, model: *mut GRBmodel) -> Model<'a>

create an empty model which associated with certain environment.

fn update(&mut self) -> Result<()>

apply all modification of the model to process.

fn copy(&self) -> Result<Model>

create a copy of the model

fn optimize(&mut self) -> Result<()>
