Struct VersionNotAvailable 

pub struct VersionNotAvailable {
    pub required: Version,
    pub negotiated: Version,
}

A RequireVersion demand the connection in hand does not satisfy.

Carries both halves, because “HTTP/2 was required” and “HTTP/1.1 is what this connection negotiated” are separately actionable — the first is the caller’s own request coming back, the second is a fact about the server or the TLS configuration.

One type in this crate rather than one per backend (the shape hclient_h3::RequestTrailersNotSent takes), because a caller downcasting on it must not have to know which transport is underneath: the demand is portable, so its refusal is too.

Fields

required: Version

negotiated: Version
