Enum curl::easy::HttpVersion

#[non_exhaustive]
pub enum HttpVersion {
    Any,
    V10,
    V11,
    V2,
    V2TLS,
    V2PriorKnowledge,
    V3,
}

Possible values to pass to the http_version method.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Any

We don’t care what http version to use, and we’d like the library to choose the best possible for us.

V10

Please use HTTP 1.0 in the request

V11

Please use HTTP 1.1 in the request

V2

Please use HTTP 2 in the request (Added in CURL 7.33.0)

V2TLS

Use version 2 for HTTPS, version 1.1 for HTTP (Added in CURL 7.47.0)

V2PriorKnowledge

Please use HTTP 2 without HTTP/1.1 Upgrade (Added in CURL 7.49.0)

V3

Setting this value will make libcurl attempt to use HTTP/3 directly to server given in the URL. Note that this cannot gracefully downgrade to earlier HTTP version if the server doesn’t support HTTP/3.

For more reliably upgrading to HTTP/3, set the preferred version to something lower and let the server announce its HTTP/3 support via Alt-Svc:.

(Added in CURL 7.66.0)
