You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: example_powcone.rs
    path of file: ./repos/Clarabel.rs/examples/rust
    
    the code of the file until where you have to start completion: #![allow(non_snake_case)]

// Power Cone Example
//
//  solve the following power cone problem
//  max  x1^0.6 y^0.4 + x2^0.1
//  s.t. x1, y, x2 >= 0
//       x1 + 2y  + 3x2 == 3
//  which is equivalent to
//  max z
