Implementations

impl Api

pub fn new(config: Config) -> Self

Create a new API client.

Arguments

• config - the configuration

Examples

let config = Config::load_config().expect("Could not load config");
let mut api = Api::new(config);

pub fn do_login(&mut self) -> Result<(), ApiError>

Uses the values from the config to get an access token from the OAuth endpoint, and stores it in the struct.

This method should be called after creating the struct, and before attempting to query any inforamtion from the API.

Examples

if let Err(err) = api.do_login() {
    panic!("Could not get an access token: {}", err);
}

pub fn get_whoami(&self) -> Result<Value, ApiError>

Returns the account’s username from the ‘api/v1/me’ endpoint.

Examples

let whoami = match api.get_whoami() {
    Ok(data) => data,
    Err(err) => panic!(err),
};

pub fn get_username(&self) -> Option<String>

Returns the username from the stored whoami data.

Examples

let username = match api.get_username() {
    Ok(data) => data,
    Err(err) => panic!(err),
};

pub fn query( &self, method: &str, path: &str, query: Option<Vec<(&str, &str)>>, form_data: Option<HashMap<&str, &str>>, ) -> Result<Response, ApiError>

Query the Reddit API.

Arguments

• method - A string representing an HTTP method, capable of being parsed by reqwest, i.e. “GET”, “POST”, etc.
• path - A relative URL path (everything after reddit.com/)
• query - An optional collection of query parameters
• form_data - An optional collection of form data to submit

let mut post_data = HashMap::new();
post_data.insert("id", "t3_aaaaaa");
match api.query("POST", "api/save", None, Some(post_data)) {
    Ok(data) => println!("{}", data),
    Err(err) => panic!(err),
}

pub fn query_listing( &self, ql: QueryListingRequest<'_>, ) -> Result<Vec<Value>, ApiError>

Query the Reddit API via a listing endpoint.

Information on listing endpoints can be found in the offial docs.

Examples

let ql = QueryListingRequest::new("r/rust/hot", 1, 1);
let data: Vec<Value> = api.query_listing(ql).unwrap();
println!("{:?}", data);

pub fn search_for_subreddit( &self, name: &str, ) -> Result<Vec<Subreddit<'_>>, ApiError>
