Module node 

Structs

FileIter

Iterates over all files in the cache (skipping directories).

NodeCache

NodeCache is an in-memory cache of weak node references.

OpenedNode

PlaceholderOwner

PlaceholderOwner is a reserved slot in the node cache.

WeakNode

WeakNode permits upgrade_and_downcast_node below which only tries to upgrade if we know the downcast will work. This makes for a simpler and more performant implementation of FileIter which would otherwise have to jump through some hoops to drop the reference count whilst not holding locks if the downcast fails.

Enums

GetResult

See NodeCache::get_or_reserve.

Traits

FxNode

FxNode is a node in the filesystem hierarchy (either a file or directory).

ToWeakNode

Used to convert nodes into WeakNode which is stored in the cache. This should be implemented using the ToWeakNode derive macro.
