memofs

Implementation of a virtual filesystem with a configurable backend and file watching.

memofs is currently an unstable minimum viable library. Its primary consumer is Rojo, a build system for Roblox.

Current Features

• API similar to std::fs
• Configurable backends
  • StdBackend, which uses std::fs and the notify crate
  • NoopBackend, which always throws errors
  • InMemoryFs, a simple in-memory filesystem useful for testing

Future Features

• Hash-based hierarchical memoization keys (hence the name)
• Configurable caching (write-through, write-around, write-back)
