Struct memofs::InMemoryFs

pub struct InMemoryFs { /* fields omitted */ }

In-memory filesystem that can be used as a VFS backend.

Internally reference counted to enable giving a copy to Vfs and keeping the original to mutate the filesystem’s state with.

Implementations

impl InMemoryFs

pub fn new() -> Self

Create a new empty InMemoryFs.

pub fn load_snapshot<P: Into<PathBuf>>(
    &mut self,
    path: P,
    snapshot: VfsSnapshot
) -> Result<()>

Load a VfsSnapshot into a subtree of the in-memory filesystem.

This function will return an error if the operations required to apply the snapshot result in errors, like trying to create a file inside a file.

pub fn raise_event(&mut self, event: VfsEvent)

Raises a filesystem change event.

If this InMemoryFs is being used as the backend of a Vfs, then any listeners be notified of this event.
