ScanContext

class ScanContext(generator, cleanup_func)

Bases: AbstractContextManager[Iterator[T]], Generator[T, None, None], Generic[T]

Context manager wrapper for scan operations that ensures proper cleanup.

Implements two use cases:

• Recommended: ContextManager over Iterator[T] for use with ‘with’ statements

• Legacy: Generator[T] for direct iteration (issues deprecation warning)

When used without entering the context manager, a deprecation warning is issued.

Note

This is a generic class parameterized by type T, which represents the type of items yielded by the generator.

Methods Summary

close()	Close the generator and perform cleanup.
send(value)	Send a value to the generator (required by Generator protocol).
throw(typ[, val, tb])	Throw an exception into the generator (required by Generator protocol).
