Enum Protocol 

#[non_exhaustive]
pub enum Protocol {
    Sslv3,
    Tlsv10,
    Tlsv11,
    Tlsv12,
    Tlsv13,
}

SSL/TLS protocol versions.

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.

Sslv3

The SSL 3.0 protocol is insecure. Don’t use it.

Warning

SSL 3.0 has severe security flaws, and should not be used unless absolutely necessary. If you are not sure if you need to enable this protocol, you should not.

Tlsv10

The TLS 1.0 protocol is insecure. Don’t use it.

Warning

Deprecated in 2021 (RFC 8996)

Tlsv11

The TLS 1.1 protocol.

Warning

Deprecated in 2021 (RFC 8996)

Tlsv12

The TLS 1.2 protocol.

Tlsv13

The TLS 1.3 protocol. Not supported on macOS/iOS.

Apple platforms will fall back to TLS 1.2 when it’s allowed by the minimum protocol version setting, or fail due to lack of TLS 1.3 support (with error -9830).
