Enum SslMode 

pub enum SslMode {
    Disable,
    Prefer,
    Require,
    VerifyCa,
    VerifyFull,
}

SSL mode for connections.

With the default tls cargo feature, Require/VerifyCa/VerifyFull establish rustls-encrypted connections verified against the Mozilla root store. Prefer uses TLS when the server offers it and falls back to plaintext only when the server declines TLS (note: stricter than libpq — a certificate verification failure fails the connection rather than retrying plaintext). Without the tls feature, TLS-requiring modes fail at pool build time.

Variants

Disable

Disable SSL.

Prefer

Prefer SSL but allow non-SSL when the server declines TLS.

Require

Require SSL. Certificates are verified (chain + hostname) — stricter than libpq’s require, which skips verification.

VerifyCa

Require SSL and verify the certificate chain. Currently also verifies the hostname (i.e. behaves as VerifyFull; libpq’s hostname-less verify-ca is not yet distinguished).

VerifyFull

Require SSL and verify the certificate chain and hostname.
