Struct Ext2Params 

pub struct Ext2Params {
    pub device_path: Option<String>,
    pub device_id: Option<usize>,
    pub options: BTreeMap<String, String>,
}

ext2 filesystem parameters for mount options

This struct holds the parameters parsed from mount option strings and provides the interface for creating ext2 filesystems.

Fields

device_path: Option<String>

Device file path (e.g., “/dev/vda”)

device_id: Option<usize>

Block device ID (if resolved)

options: BTreeMap<String, String>

Mount options

Implementations

impl Ext2Params

pub fn new() -> Self

Expected format: “device=/dev/vda,rw,sync” or: “device=/dev/vda,ro”

pub fn resolve_device(&mut self) -> Result<(), FileSystemError>

Resolve device path to device ID

pub fn get_device_id(&self) -> Option<usize>

Get the resolved device ID

pub fn get_option(&self, key: &str) -> Option<&String>

Get a specific option value

pub fn is_readonly(&self) -> bool

Check if filesystem should be mounted read-only

pub fn create_filesystem( &mut self, ) -> Result<Arc<Ext2FileSystem>, FileSystemError>

Create ext2 filesystem from these parameters
