[![GitHub last commit](https://img.shields.io/github/last-commit/barrowsys/napchart-rs)](https://github.com/barrowsys/napchart-rs) //! [![Crates.io](https://img.shields.io/crates/v/napchart)](https://crates.io/crates/napchart/) //! [![Docs.rs](https://docs.rs/napchart/badge.svg)](https://docs.rs/napchart) //! //! A strongly-typed rust interface to the <https://napchart.com> API. //! //! The public napchart api is pretty barebones right now, but this will let you use it! //! //! ## Usage //! //! Add to your Cargo.toml: //! ```text //! [dependencies] //! napchart = "0.3" //! ``` //! //! ## Examples //! //! ### Creating a new napchart from scratch //! Example: <https://napchart.com/snapshot/O6kunUfuL> //! ``` //! use napchart::prelude::*; //! //! let mut chart = Napchart::default() //! .shape(ChartShape::Circle) //! .lanes(1); //! let first_lane = chart.get_lane_mut(0).unwrap(); //! first_lane.add_element(0, 60).unwrap() //! .text("Hour One"); //! first_lane.add_element(180, 240).unwrap() //! .text("Hour Four"); //! let second_lane = chart.add_lane(); //! second_lane.add_element(0, 120).unwrap() //! .color(ChartColor::Blue); //! second_lane.add_element(120, 240).unwrap() //! .color(ChartColor::Green) //! .text("Cool green time"); //! ``` //! //! ### Downloading a napchart //! Example Chart: <https://napchart.com/3tbkt> //! ``` //! use napchart::api::BlockingClient; //! //! let client = BlockingClient::default(); //! let rchart = client.get_chart("3tbkt").unwrap(); //! assert_eq!(rchart.chartid, String::from("3tbkt")); //! assert_eq!(rchart.title, Some(String::from("State test chart"))); //! assert_eq!(rchart.chart.shape, napchart::ChartShape::Circle); //! assert_eq!(rchart.chart.lanes_len(), 1); //! ``` //! //! ### Uploading a napchart as a snapshot //! Example Output: <https://napchart.com/snapshot/TpCfggr4i> //! ```no_run //! use napchart::prelude::*; //! use napchart::api::BlockingClient; //! //! let client = BlockingClient::default(); //! let mut chart = Napchart::default(); //! let lane = chart.add_lane(); //! lane.add_element(420, 1260) //! .unwrap() //! .text("Nighttime") //! .color(ChartColor::Gray); //! let upload_builder = chart.upload() //! .title("readme doctest") //! .description("https://crates.io/crates/napchart");
