Struct ClientBuilder 

pub struct ClientBuilder { /* private fields */ }

Construct a WebTransport Client using sensible defaults.

This is optional; advanced users may use Client::new directly.

Implementations

impl ClientBuilder

pub fn new() -> Self

Create a client builder, which can establish multiple Sessions.

pub fn with_congestion_control(self, algorithm: CongestionControl) -> Self

Enable the specified congestion controller.

pub fn with_transport_config(self, transport: TransportConfig) -> Self

Replace the QUIC transport configuration.

Use this to configure idle timeouts, receive windows, concurrent stream limits, datagram buffers, and other transport resource limits.

pub fn with_dns_timeout(self, timeout: Duration) -> Self

Limit how long DNS resolution may take.

pub fn with_handshake_timeout(self, timeout: Duration) -> Self

Limit the combined QUIC, HTTP/3 SETTINGS, and CONNECT handshake duration.

pub fn with_system_roots(self) -> Result<Client, ClientError>

Accept certificates from servers chained to known root CAs.

pub fn with_server_certificates( self, certs: Vec<CertificateDer<'_>>, ) -> Result<Client, ClientError>

Supply certificates for accepted servers instead of using root CAs.

pub fn with_server_certificate_hashes( self, hashes: Vec<Vec<u8>>, ) -> Result<Client, ClientError>

Supply SHA-256 hashes for accepted certificates instead of using root CAs.

pub fn dangerous(self) -> DangerousClientBuilder

Access dangerous configuration options.

This method returns a builder that provides access to potentially insecure TLS configurations. These options are opt-in and require explicit acknowledgment through the builder pattern, making the security implications clear at the call site.
