Implementations

impl PgMetadataAdapter

pub fn new(connection_info: impl Into<String>) -> Self

Creates an adapter from an existing libpq-style connection string.

pub fn direct(config: DirectPostgresConnectConfig) -> Self

Creates an adapter from structured direct connection settings.

pub fn direct_with_ca( config: DirectPostgresConnectConfig, root_certificates: Vec<String>, ) -> Self

Creates a direct adapter with an explicit additional CA bundle.

pub fn direct_with_ca_and_routing_address( config: DirectPostgresConnectConfig, routing_address: Option<&str>, root_certificates: Vec<String>, ) -> Self

Creates a direct adapter that routes transport separately while TLS continues to verify the configured logical host.

pub fn connection_description(&self) -> &str

Returns the connection description safe for logs and diagnostics.

pub fn connect_observed( &self, context: Option<&CorrelationContext>, ) -> Result<PgMetadataConnection, PgMetaError>

Opens a correlated read capability. Emits one connection event and one query-stage summary when the operation-scoped connection is released.

pub fn connect(&self) -> Result<PgMetadataConnection, PgMetaError>

Opens a direct PostgreSQL metadata connection.

Errors

Returns an error if TLS configuration cannot be built or PostgreSQL rejects the connection.
