pub struct DeviceFileSystem { /* private fields */ }
Expand description

A device filesystem that implements axfs_vfs::VfsOps.

Implementations§

source§

impl DeviceFileSystem

source

pub fn new() -> Self

Create a new instance.

source

pub fn mkdir(&self, name: &'static str) -> Arc<DirNode>

Create a subdirectory at the root directory.

source

pub fn add(&self, name: &'static str, node: VfsNodeRef)

Add a node to the root directory.

The node must implement axfs_vfs::VfsNodeOps, and be wrapped in Arc.
