pub fn parse_alter_session_value(statement: &str, key: &str) -> Option<String>Expand description
Parses the value assigned by an ALTER SESSION SET <key> = <value> statement,
case-insensitively, returning the (unquoted) value when statement is exactly
that alter for key. Used to track session state (e.g. current_schema,
edition) that the server reflects back without a round trip (reference
connection.pyx reads these from the executed alter session). Pure driver
logic lifted out of the PyO3 shim (bead p5o).
