Detailed Description

The nodes library's exception boundary.

Compiled with exceptions (see the exception policy block in cpp/CMakeLists.txt). A NodeMap's factory is the caller's – often a Python callable that builds a ChunkStore per node id – and NodeMap invokes it from its own frames, so it is wrapped here where a raised exception can still be caught. a11/exception_guard.h has the reasoning.
