VirtualFileSystem

File layer abstracting the handling of in-memory files and concrete filesystem files.

This struct abstracts and contains those differences.

The lookup rule for a filename is: - in-memory container. - load from the filesystem.

TODO Is it better to have everything as MMF? I think it would be possible to have the source code as an anonymous MMF.

struct VirtualFileSystem {

Postblit

Copying this object is disabled.

A postblit is present on this object, but not explicitly documented in the source.

files auto files(): Trusted on the assumption that byKey is @safe _enough_.
open void open(FileName fname, Mode mode = Mode.read): Add a mapping to a concrete file.
openInMemory void openInMemory(FileName fname): Create an in-memory file.
write void write(FileName fname, Content content): Write to a file.
