Detailed Description

A function object that copies data from a source context to a destination context.

The copy_fn struct defines a function call operator that takes a source context and a destination context as parameters. It performs the copy operation, transferring data from the source to the destination. The source context includes information about the database (container) connection, columns to be copied, and any filters to be applied. The destination context specifies the target path and schema for the copied data. This allows for efficient duplication of data between different contexts in the database.
