lta-rs

lta-rs is a lta datamall client library written in pure safe rust. lta-rs is used to interact with the lta-datamall

lta-rust in action

Cargo.toml setup

There are various versions available. If you omit branch = "version_no", you are taking it from master branch The library is also available on crates.io toml [dependencies] lta = "0.2.2"

API key setup

You can get your API key from here

```rust extern crate lta;

use lta::lta_client::*;

fn main() { let apikey = "MYAPIKEY"; let client = LTAClient::withapikey(apikey); }

```

Examples

Getting bus timings ```rust use lta::bus::getarrival; use lta::ltaconfig::*;

fn getarrivals(client: &LTAClient) { let resp: Result = getarrival(client, 83139, "15"); match resp { Ok(busarrivalresp) => println!("{:?}", busarrivalresp), Err(e) => println!("{:?}", e) }; } ```

Getting anything else ``rust // All the APIs in this library are designed to be used like this //module::getsomething` // All of them return Result, Error> // The example below is bus::getbusservices() // and traffic::geterprates() // Do note that the API is similar across all the APIs except for // bus::getarrival use lta::bus::getbusservices; use lta::traffic::geterprates; use lta::lta_config::*;

fn getbusservices(client: &LTAClient) { let resp: Result, Error> = getbusservices(client); match resp { Ok(r) => println!("{:?}", r), Err(e) => println!("{:?}", e) }; }

fn geterprates(client: &LTAClient) { let resp: Result, Error> = geterprates(client); match resp { Ok(r) => println!("{:?}", r), Err(e) => println!("{:?}", e) }; } ```

You can get help via github issues. I will try my best to respond to your queries :smile:

Design decisions

Made sure that Rust structs are as close to the original response as possible to make sure that people can reference the original docs if there are any issues
Simple and no additional baggage. Only the client is included. E.g If anyone wants to add concurrency, they have to do it on their own

Changelog

Version 0.1 - All endpoints that are available from lta datamall website - Configuration using API

Version 0.2 [ Breaking Changes ] - Changed all API to take in &LTAClient rather than using a global LTAClient

Version 0.2.1 - Updated dependencies to latest version as of 21 July 2019

Version 0.2.2 - Updated LTAClient::with_api_key to create a LTAClient

Todo (excluding bugs from issues)

[x] Proper date types using chrono library
[x] Utils cleanup
[x] Host on crates.io
[ ] Static website to showcase project
[x] Documentation
[x] More idiomatic Rust code

Frequently Asked Questions

Where do I get the official docs from lta?

You can get them here

Why are some of the datatypes different from the lta documentation?

Some of the datatypes returned are not ideal such as returning lat and lang as string rather than number. Some of the types are also converted to enums to reduce the number of stringly typed stuff

My application panicked.

Check if your API key is valid, if it is and your application still panics because of this library, create a github issue

Is this project affiliated to LTA or any government bodies?

No.
