Struct ethcontract::prelude::Http

pub struct Http { /* private fields */ }

HTTP Transport

Implementations

impl Http

pub fn new(url: &str) -> Result<Http, Error>

Create new HTTP transport connecting to given URL.

Note that the http Client automatically enables some features like setting the basic auth header or enabling a proxy from the environment. You can customize it with Http::with_client.

pub fn with_client(client: Client, url: Url) -> Http

Like new but with a user provided client instance.

fn send_batch<T>(&self, requests: T) -> <Http as BatchTransport>::Batch

where T: IntoIterator<Item = (usize, Call)>,
