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: hash.rs
    path of file: ./repos/polars/crates/polars-plan/src/logical_plan/aexpr
    
    the code of the file until where you have to start completion: use std::hash::{Hash, Hasher};

use crate::prelude::AExpr;

impl Hash for AExpr {
    // This hashes the variant, not the whole expression
    fn hash<H: Hasher>(&self, state: &mut H) {
        std::mem::discriminant(self).hash(state);

        match self {
            AExpr::Column(name) => name.hash(state),
            AExpr::Alias(_, name) => name.hash(state),
            AExpr::Nth(v) => v.hash(state),
            AExpr::Literal(lv) => lv.hash(state),
            AExpr::Function {
                options, function, ..
            } => {
                options.hash(state);
                function.hash(state)
            },
            AExpr::AnonymousFunction { options, .. } => {
                options.hash(state);
            },
            AExpr::Agg(agg) => agg.hash(sta
    
    fn hash<H: Hasher>(&self, state: &mut H) {
        std::mem::discriminant(self).hash(state);

        match self {
            AExpr::Column(name) => name.hash(state),
            AExpr::Alias(_, name) => name.hash(state),
            AExpr::Nth(v) => v.hash(state),
            AExpr::Literal(lv) => lv.hash(state),
            AExpr::Function {
                options, function, ..
            } => {
                options.hash(state);
                function.hash(state)
            },
            AExpr::AnonymousFunction { options, .. } => {
                options.hash(state);
            },
            AExpr::Agg(agg) => agg.hash(state),
            AExpr::SortBy { descending, .. } => descending.hash(state),
            AExpr::Cast { strict, .. } => strict.hash(state),
            AExpr::Window { options, .. } => options.hash(state),
            AExpr::BinaryExpr { op, .. } => op.hash(state),
            _ => {},
