- Introduced a `PrefetchCache` structure to store pre-read file contents and canonical paths, enhancing the speed of initial reads during snapshot building. - Implemented parallel file reading using `rayon` and `walkdir` to populate the cache efficiently. - Updated the `VfsInner` struct to include the prefetch cache and modified read methods to utilize it, reducing I/O operations. - Added functions to set and clear the prefetch cache in the `Vfs` API, improving memory management during live operations. - Enhanced tests to validate the functionality of the prefetch cache, ensuring correct behavior during file reads and canonicalization. These changes aim to significantly improve the performance of the VFS by minimizing file access times during initial operations. |

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 usesstd::fsand thenotifycrateNoopBackend, which always throws errorsInMemoryFs, 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)
