using ute

including in your project

[top]

• add this repo* to your Cargo.toml:

[dependencies]

# ... other deps are probably here ...

ute = {git = "https://github.com/parkcitymedia/ute", branch="main"}

*cargo searches by default for a "master" branch, so branch specification may/may not be necessary.

examples

using handmade or generated tiles

assuming tile path "tile.json" has been made/exists:

• map json to a tile (serde)

[top]

// likely your main.rs:
use ute::{Tile, identify_tile};
use serde_json::{from_str};
use std::fs::read_to_string;

#[tokio::main] // requires tokio = {features = ["full"]}
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    
    // where does the tile live?
    let raw_tile_path: &str = "tile.json";
    
    // read the tile info into a String (re-borrow
    // into &str for serde_json compatibility)
    let tile_r: String = read_to_string(raw_tile_path).unwrap();
    let tile_r: &str = &tile_r;

    // use serde_json::from_str() to
    // map the json string to a pantsemm::Tile
    // note: this tile is mutable - while they don't
    // need to be, this is good for when
    // you want to change tile field values later
    let mut tile: Tile = from_str(tile_r)?;
    
    // generate a unique tile-data-based tile name
    // with pantsemm's pantsemm::identify_tile()
    // (returns a Tile!!! common use: mutation)
    tile = identify_tile(&mut tile)?;

    // print the tile_id out after generating it!
    println!("my new tile id: {:#?}", tile.tile_id);

    Ok(())
}

single tile input

[top]

an example can be found in tiles/tile_example.jsonof a handwritten/generated hexagon for data input. here's an example quad/square to look at right now: quad_example.json
