Struct ConnectOptions 

pub struct ConnectOptions {
    pub tls_mode: TlsMode,
    pub gss_enc_mode: GssEncMode,
    pub tls_ca_cert_pem: Option<Vec<u8>>,
    pub mtls: Option<TlsConfig>,
    pub gss_token_provider: Option<GssTokenProvider>,
    pub gss_token_provider_ex: Option<GssTokenProviderEx>,
    pub auth: AuthSettings,
    pub startup_params: Vec<(String, String)>,
}

Advanced connection options for enterprise deployments.

Protocol-version controls are intentionally not exposed here in this milestone. The driver requests protocol 3.2 by default and performs a one-shot fallback to protocol 3.0 only on explicit version rejection.

Fields

tls_mode: TlsMode

TLS mode for the primary connection.

gss_enc_mode: GssEncMode

GSSAPI session encryption mode.

tls_ca_cert_pem: Option<Vec<u8>>

Optional custom CA bundle (PEM) for TLS server validation.

mtls: Option<TlsConfig>

Optional mTLS client certificate/key config.

gss_token_provider: Option<GssTokenProvider>

Optional callback for Kerberos/GSS/SSPI token generation.

gss_token_provider_ex: Option<GssTokenProviderEx>

Optional stateful Kerberos/GSS/SSPI token provider.

auth: AuthSettings

Password-auth policy.

startup_params: Vec<(String, String)>

Additional startup parameters sent in StartupMessage. Example: replication=database for logical replication mode.

Implementations

impl ConnectOptions

pub fn with_startup_param( self, key: impl Into<String>, value: impl Into<String>, ) -> Self

Add a startup parameter.

Example: opts.with_startup_param("application_name", "qail-repl").

pub fn with_logical_replication(self) -> Self

Enable logical replication startup mode (replication=database).

Trait Implementations

impl Clone for ConnectOptions

fn clone(&self) -> ConnectOptions

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConnectOptions

fn default() -> ConnectOptions

Returns the “default value” for a type.
