Struct EmptyEnv

pub struct EmptyEnv { /* private fields */ }

Gurobi environment object (see the Gurobi manual) A Gurobi environment which hasn’t been started yet. Some Gurobi parameters, such as Record need to be set before the environment has been started.

Setting param::OutputFlag to 0 on an EmptyEnv is useful for stopping the license info from being printed, since this happens on starting the environment.

Examples

use grb::*;
let mut env = Env::empty()?;
env.set(param::OutputFlag, 0)? // license will not be printed when env starts
  .set(param::UpdateMode, 1)?
  .set(param::LogFile, "".to_string())?;
let env : Env = env.start()?;
