Struct DevFS

pub struct DevFS {
    root: RwLock<Arc<DevNode>>,
    name: String,
}

DevFS - Device filesystem implementation

This filesystem automatically exposes all devices registered in the global DeviceManager as device files. It provides a virtual view of the system’s devices, similar to /dev in Unix-like systems.

Fields

root: RwLock<Arc<DevNode>>

Root directory node

name: String

Filesystem name

Implementations

impl DevFS

pub fn new() -> Arc<Self>

Create a new DevFS instance

fn populate_devices(&self) -> Result<(), FileSystemError>

Populate the filesystem with current devices from DeviceManager
