A runtime error encountered within a data source connector.
A runtime error encountered within a data source connector. A user isn't expected to usually be able to handle these as they likely arise from a defect or an "environmental" issue (memory, network, storage, etc).
This should not be used to communicate configuration/validation errors at mount-time as DefinitionError is more appropriate in that case.

FileSystem interpreters for a filesystem that has no, and doesn't support creating any, files.

object InMemory

In-Memory FileSystem interpreters, useful for testing/stubbing when a "real" interpreter isn't needed or desired.

NB: Since this is in-memory, careful with writing large amounts of data to the file system.
