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: player.rs
    path of file: ./repos/rustrogueliketutorial/chapter-65-items/src
    
    the code of the file until where you have to start completion: use rltk::{VirtualKeyCode, Rltk, Point};
use specs::prelude::*;
use std::cmp::{max, min};
use super::{Position, Player, Viewshed, State, Map, RunState, Attributes, WantsToMelee, Item,
    gamelog::GameLog, WantsToPickupItem, TileType, HungerClock, HungerState,
    EntityMoved, Door, BlocksTile, BlocksVisibility, Renderable, Pools, Faction,
    raws::Reaction, Vendor, VendorMode};

pub fn try_move_player(delta_x: i32, delta_y: i32, ecs: &mut World) -> RunState {
    let mut positions = ecs.write_storage::<Position>();
    let players = ecs.read_storage::<Player>();
    let mut viewsheds = ecs.write_storage::<Viewshed>();
    let entities = ecs.entities();
    let combat_stats = ecs.read_storage::<Attributes>();

    let player_pos = ecs.fetch::<Point>();
    let player_entity = ecs.fetch::<Entity>();
    let entities = ecs.entities();
    let items = ecs.read_storage::<Item>();
    let positions = ecs.read_storage::<Position>();
    let mut gamelog = ecs.fetch_mut::<GameLog>();

    let mut target_item : Option<Entity> = None;
    for (item_entity, _item, position) in (&entities, &items, &positions).join() {
        if position.x == player_pos.x && position.y == player_pos.y {
            target_item = Some(item_entity);
        }
    }

    match target_item {
        None => gamelog.entries.push("There is nothing here to pick up.".to_string()),
        Some(item) => {
            let mut pickup = ecs.write_storage::<WantsToPickupItem>();
            pickup.insert(*player_entity, WantsToPickupItem{ collected_by: *player_entity, item }).expect("Unable to insert want to pickup");
