Cn

class Cn(rt: <Error class: unknown class><out <Error class: unknown class>>, cn: <Error class: unknown class><out <Error class: unknown class>>) : Connection(source)

Represents a database connection implementation that provides capabilities to execute SQL queries, handle transactions, and manage connection state.

This class interacts with a native PostgreSQL driver using low-level pointer-based operations, providing asynchronous capabilities through the use of coroutines and suspending functions.

Parameters

rt

A pointer to the runtime environment for the database driver.

cn

A pointer to the database connection.

Constructors

constructor(rt: <Error class: unknown class><out <Error class: unknown class>>, cn: <Error class: unknown class><out <Error class: unknown class>>)

Creates a new instance of the Cn class.
