Enum TlsVersion 

#[non_exhaustive]
pub enum TlsVersion {
    Tls12,
    Tls13,
}

TLS building blocks shared with other transport crates (e.g. the upstream proxy engine) so every outbound ClientConfig goes through the same provider selection and FIPS hardening. TLS building blocks shared with other transport crates (e.g. the upstream proxy engine) so every outbound ClientConfig goes through the same provider selection and FIPS hardening. TLS building blocks shared with other transport crates (e.g. the upstream proxy engine) so every outbound ClientConfig goes through the same provider selection and FIPS hardening. Minimum TLS protocol version the client will negotiate.

Maps onto the rustls protocol-version slice passed to ClientConfig::builder_with_provider(..).with_protocol_versions(..):

• TlsVersion::Tls12 advertises both TLS 1.2 and TLS 1.3 (the historical with_safe_default_protocol_versions() behaviour).
• TlsVersion::Tls13 advertises TLS 1.3 only.

This is a user knob; it does not relax FIPS hardening. Under --features fips, tls::apply_fips_hardening still asserts ClientConfig::fips(), so a version selection incompatible with the active FIPS provider surfaces as a crate::error::HttpError::Tls at build time.

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.

Tls12

Allow TLS 1.2 and TLS 1.3 (default — matches rustls safe defaults).

Tls13

Require TLS 1.3; reject TLS 1.2 handshakes.
