Enum ServerProtocol 

pub enum ServerProtocol {
    Http1,
    Http2,
    Http3,
}

The wire protocol a server connection speaks.

The variant is selected at runtime from the server configuration, never at compile time: one binary serves every protocol it is configured for.

Variants

Http1

HTTP/1.0 and HTTP/1.1 over a plain or TLS terminated byte stream.

Http2

HTTP/2, either with prior knowledge over a plain socket or negotiated through h2 ALPN over TLS.

Http3

HTTP/3 over QUIC, which always terminates TLS inside its own handshake.

Implementations

impl ServerProtocol

Implementation block for ServerProtocol.

pub fn get_alpn_protocol(&self) -> &'static [u8]

Returns the ALPN protocol identifier used to negotiate this protocol.

The value is sent verbatim in the TLS handshake, so it must be the wire identifier and not the human-readable version string.

Returns

• &'static [u8] - The ALPN protocol identifier bytes.

pub fn get_version(&self) -> HttpVersion

Returns the HTTP version negotiated by this protocol.

Returns

• HttpVersion - The protocol’s HTTP version.

pub fn is_quic(&self) -> bool

Returns true when this protocol runs over QUIC rather than TCP.

Returns

• bool - true for QUIC transports, false for TCP transports.
