Struct TungsteniteTransport 

pub struct TungsteniteTransport { /* private fields */ }

The native transport: tokio-tungstenite over TCP, with TLS from rustls.

It installs the rustls CryptoProvider before it dials (ensure_crypto_provider), since a consumer that builds two rustls backends gets no default and a direct connect would panic. Its capabilities are all true.

Implementations

impl TungsteniteTransport

pub const fn new() -> Self

The plain dial: tungstenite’s own connect, which resolves the host and connects to the first address it returns.

pub const fn per_address() -> Self

The dial of a host that has several addresses, some of which may not answer: it resolves every address up front, tries each in family-interleaved order (IPv6 and IPv4 alternating, RFC 8305 section 4), and bounds the TCP connect and, separately, the TLS and WebSocket upgrade of each by the connect timeout, so a blackholed route costs one timeout and not one per address. It falls back to the next address on any failure but a refused upgrade, which it returns at once: another address would repeat the refusal, and its own failure would hide this one’s status and Retry-After.
