CapsuleHandshakeError

rama::http::datagram::handshake

Enum CapsuleHandshakeError 

pub enum CapsuleHandshakeError {
    UnsupportedVersion(Version),
    NotAnUpgrade,
    ConnectionSpecificField(HeaderName),
    Unsuccessful(StatusCode),
    ForbiddenField(HeaderName),
    ForbiddenStatus(StatusCode),
    UpgradeMismatch,
}
Available on crate features http and std only.
Expand description

A handshake that cannot start or accept the Capsule Protocol.

Variants§

§

UnsupportedVersion(Version)

The HTTP version cannot carry an upgrade token (HTTP/1.0 and earlier).

§

NotAnUpgrade

The request is neither an HTTP/1.1 upgrade nor Extended CONNECT.

§

ConnectionSpecificField(HeaderName)

An HTTP/2 or HTTP/3 message carries a connection-specific upgrade field.

§

Unsuccessful(StatusCode)

The response refused the upgrade; its content is an ordinary HTTP message.

§

ForbiddenField(HeaderName)

A field the Capsule Protocol forbids: the message is malformed.

§

ForbiddenStatus(StatusCode)

A status the Capsule Protocol forbids (204, 205, 206): the message is malformed.

§

UpgradeMismatch

The HTTP/1.1 101 response does not switch to the requested protocol.
