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: mod.rs
    path of file: ./repos/Daft/src/daft-dsl/src/functions/numeric
    
    the code of the file until where you have to start completion: mod abs;
mod ceil;
mod floor;

use abs::AbsEvaluator;
use ceil::CeilEvaluator;
use floor
    
    pub fn get_evaluator(&self) -> &dyn FunctionEvaluator {
        use NumericExpr::*;
        match self {
            Abs => &AbsEvaluator {},
            Ceil => &CeilEvaluator {},
            Floor => &FloorEvaluator {},
        }
    }
