Enum HttpVersion

#[non_exhaustive]
pub enum HttpVersion {
    Any = 0,
    V10 = 1,
    V11 = 2,
    V2 = 3,
    V2TLS = 4,
    V2PriorKnowledge = 5,
    V3 = 30,
}

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 = 0

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

V10 = 1

Please use HTTP 1.0 in the request

V11 = 2

Please use HTTP 1.1 in the request

V2 = 3

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

V2TLS = 4

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

V2PriorKnowledge = 5

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

V3 = 30

Setting this value will make libcurl attempt to use HTTP/3 directly to server given in the URL but fallback to earlier HTTP versions if the HTTP/3 connection establishment fails.

Note: the meaning of this settings depends on the linked libcurl. For CURL < 7.88.0, there is no fallback if HTTP/3 connection fails.

(Added in CURL 7.66.0)
