Struct WsClientBuilder

Source

pub struct WsClientBuilder<RpcMiddleware = Stack<RpcLoggerLayer, Identity>> { /* private fields */ }

Expand description

Builder for WsClient.

§Examples


use jsonrpsee_ws_client::{WsClientBuilder, HeaderMap, HeaderValue};

#[tokio::main]
async fn main() {
    // Build custom headers used during the handshake process.
    let mut headers = HeaderMap::new();
    headers.insert("Any-Header-You-Like", HeaderValue::from_static("42"));

    // Build client
    let client = WsClientBuilder::default()
         .set_headers(headers)
         .build("wss://localhost:443")
         .await
         .unwrap();

    // use client....
}

Implementations§

Source §

impl WsClientBuilder

Source

pub fn new() -> WsClientBuilder

Create a new WebSocket client builder.

Source §

impl<RpcMiddleware> WsClientBuilder<RpcMiddleware>

Source

pub fn with_custom_cert_store(self, cfg: CustomCertStore) -> Self

Force to use a custom certificate store.

§Optional

This requires the optional tls feature.

§Example

use jsonrpsee_ws_client::{WsClientBuilder, CustomCertStore};
use rustls::{
    client::danger::{self, HandshakeSignatureValid, ServerCertVerified},
    pki_types::{CertificateDer, ServerName, UnixTime},
    Error,
};

#[derive(Debug)]
struct NoCertificateVerification;

impl rustls::client::danger::ServerCertVerifier for NoCertificateVerification {
    fn verify_server_cert(
        &self,
        _: &CertificateDer<'_>,
        _: &[CertificateDer<'_>],
        _: &ServerName<'_>,
        _: &[u8],
        _: UnixTime,
    ) -> Result<ServerCertVerified, Error> {
        Ok(ServerCertVerified::assertion())
    }

    fn supported_verify_schemes(&self) -> Vec<rustls::SignatureScheme> {
        vec![rustls::SignatureScheme::ECDSA_NISTP256_SHA256]
    }

    fn verify_tls12_signature(
        &self,
        _: &[u8],
        _: &CertificateDer<'_>,
        _: &rustls::DigitallySignedStruct,
    ) -> Result<rustls::client::danger::HandshakeSignatureValid, Error> {
        Ok(HandshakeSignatureValid::assertion())
    }

    fn verify_tls13_signature(
        &self,
        _: &[u8],
        _: &CertificateDer<'_>,
        _: &rustls::DigitallySignedStruct,
    ) -> Result<HandshakeSignatureValid, Error> {
        Ok(HandshakeSignatureValid::assertion())
    }
}

let tls_cfg = CustomCertStore::builder()
   .dangerous()
   .with_custom_certificate_verifier(std::sync::Arc::new(NoCertificateVerification))
   .with_no_client_auth();

// client builder with disabled certificate verification.
let client_builder = WsClientBuilder::new().with_custom_cert_store(tls_cfg);

§Panics

Panics if being called outside of tokio runtime context.

Source

pub async fn build<S>(self, url: impl AsRef<str>) -> Result<WsClient<S>, Error>
where RpcMiddleware: Layer<RpcService, Service = S> + Clone + Send + Sync + 'static,

Build the WsClient with specified URL to connect to, using the default WsTransportClientBuilder::build_with_stream, therefore with the default TCP as transport layer.
