Expand description

Read the target HTTP Version a connector should establish.

This is deliberately separate from HttpVersionInputExt, which may resolve the original client version from forwarded request context. A connector needs the selected egress version instead.

Required Methods§

fn target_http_version(&self) -> Option<Version>

The selected egress HTTP version, or None if none is available.

Provided Methods§

fn target_http_version_with_fallback( &self, fallback: Option<Version>, ) -> Option<Version>

Resolve the selected egress HTTP version with a post-negotiation fallback.

Implementations that can distinguish an explicit target from an implicit input version should override this method so fallback is considered between those two sources.
