Struct Client 

pub struct Client { /* private fields */ }

A client used to send requests to Piston.

Implementations

impl Client

pub fn new() -> Self

Creates a new client.

Returns

• Client - The new Client.

Example

let client = piston_rs::Client::new();

assert!(client.get_headers().contains_key("Accept"));
assert!(client.get_headers().contains_key("User-Agent"));
assert!(!client.get_headers().contains_key("Authorization"));

pub fn with_url(url: &str) -> Self

Creates a new Client with a url that runs the piston code execution engine.

This makes it possible to interact with a self-hosted instance of piston.

Arguments

• url - The url to use as the underlying piston backend.

Returns

• Client - The new Client.

Example

let client = piston_rs::Client::with_url("http://localhost:3000");
assert_eq!(client.get_url(), "http://localhost:3000");

pub fn with_key(key: &str) -> Self

Creates a new client, with an api key.

Arguments

• key - The api key to use.

Returns

• Client - The new Client.

Example

let client = piston_rs::Client::with_key("123abc");

assert!(client.get_headers().contains_key("Authorization"));
assert_eq!(client.get_headers().get("Authorization").unwrap(), "123abc");

pub fn with_url_and_key(url: &str, key: &str) -> Self

Creates a new Client using a url and an api key.

Arguments

• url - The url to use as the underlying piston backend.
• key - The api key to use.

Returns

• Client - The new Client.

Example

let client = piston_rs::Client::with_url_and_key("http://localhost:3000", "123abc");
assert_eq!(client.get_url(), "http://localhost:3000");
assert!(client.get_headers().contains_key("Authorization"));
assert_eq!(client.get_headers().get("Authorization").unwrap(), "123abc");

pub fn get_url(&self) -> String

The base url for the Piston V2 API that is being used by this client.

Returns

• String - The requested url.

Example

let client = piston_rs::Client::new();

assert_eq!(client.get_url(), "https://emkc.org/api/v2/piston".to_string());

pub fn get_headers(&self) -> HeaderMap

The headers being used by this client.

Returns

• HeaderMap - A map of Header key, value pairs.

Example

let client = piston_rs::Client::new();
let headers = client.get_headers();

assert_eq!(headers.get("Accept").unwrap(), "application/json");

pub async fn fetch_runtimes(&self) -> Result<Vec<Runtime>, Box<dyn Error>>

Fetches the runtimes from Piston. This is an http request.

Returns

• Result<Vec<Runtime>, Box<dyn Error>> - The available runtimes or the error, if any.

Example

let client = piston_rs::Client::new();

if let Ok(runtimes) = client.fetch_runtimes().await {
    assert!(!runtimes.is_empty());
} else {
    // There was an error contacting Piston.
}

pub async fn execute( &self, executor: &Executor, ) -> Result<ExecResponse, Box<dyn Error>>

Executes code using a given executor. This is an http request.

Arguments

• executor - The executor to use.

Returns

• Result<ExecutorResponse, Box<dyn Error>> - The response from Piston or the error, if any.

Example

let client = piston_rs::Client::new();
let executor = piston_rs::Executor::new()
    .set_language("rust")
    .set_version("1.50.0")
    .add_file(piston_rs::File::default().set_content(
        "fn main() { println!(\"42\"); }",
    ));

if let Ok(response) = client.execute(&executor).await {
    assert!(response.compile.is_some());
    assert!(response.run.is_ok());
    assert!(response.is_ok());
} else {
    // There was an error contacting Piston.
}

Trait Implementations

impl Clone for Client

fn clone(&self) -> Client

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Client

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Client

fn default() -> Self

Creates a new client. Alias for Client::new.

Returns

• Client - The new Client.

Example

let client = piston_rs::Client::default();

assert!(client.get_headers().contains_key("Accept"));
assert!(client.get_headers().contains_key("User-Agent"));
assert!(!client.get_headers().contains_key("Authorization"));
assert_eq!(client.get_url(), "https://emkc.org/api/v2/piston".to_string());
