Struct MountTree

pub struct MountTree {
    pub root_mount: RwLock<Arc<MountPoint>>,
}

Mount tree manager for VFS v2

Fields

root_mount: RwLock<Arc<MountPoint>>

Root mount point (can be updated when mounting at “/”)

Implementations

impl MountTree

pub fn new(root_entry: VfsEntryRef) -> Self

Create a new mount tree with the given root

pub fn bind_mount( &self, source_entry: VfsEntryRef, target_entry: VfsEntryRef, target_mount_point: Arc<MountPoint>, ) -> VfsResult<MountId>

Create a bind mount.

Arguments

• source_entry - The VFS entry to be mounted.
• target_entry - The VFS entry where the source will be mounted.
• target_mount_point - The mount point containing the target entry.

pub fn mount( &self, target_entry: VfsEntryRef, target_mount_point: Arc<MountPoint>, filesystem: Arc<dyn FileSystemOperations>, ) -> VfsResult<MountId>

Mount a filesystem at a specific entry in the mount tree.

pub fn replace_root(&self, new_root: Arc<MountPoint>)

Replaces the root mount point.

pub fn is_mount_point( &self, entry_to_check: &VfsEntryRef, mount_point_to_check: &Arc<MountPoint>, ) -> bool

Check if a path is a mount point

Arguments

• entry_to_check - The VFS entry to check if it is a mount point.
• mount_point_to_check - The mount point to check against.

Notes

entry_to_check and mount_point_to_check should be in the same mount point.

pub fn is_bind_source(&self, entry_to_check: &VfsEntryRef) -> bool

Check if an entry is a source for a bind mount

pub fn is_entry_used_in_mount( &self, entry_to_check: &VfsEntryRef, mount_point_to_check: &Arc<MountPoint>, ) -> bool

Check if an entry is used in a mount (either as a mount point or a bind source)

pub fn unmount( &self, entry: &VfsEntryRef, parent_mount_point: &Arc<MountPoint>, ) -> VfsResult<Arc<MountPoint>>

Unmount a filesystem

pub fn resolve_path( &self, path: &str, ) -> VfsResult<(VfsEntryRef, Arc<MountPoint>)>

Resolve a path to a VFS entry, handling mount boundaries

pub fn resolve_mount_point( &self, path: &str, ) -> VfsResult<(VfsEntryRef, Arc<MountPoint>)>

Resolve a path to the mount point entry (not the mounted content) This is used for unmount operations where we need the actual mount point

pub fn resolve_path_with_options( &self, path: &str, options: &PathResolutionOptions, ) -> VfsResult<(VfsEntryRef, Arc<MountPoint>)>

Resolve a path with specified options

pub fn resolve_mount_point_with_options( &self, path: &str, options: &PathResolutionOptions, ) -> VfsResult<(VfsEntryRef, Arc<MountPoint>)>

Resolve a path to the mount point entry with options

fn resolve_path_internal( &self, path: &str, resolve_mount: bool, options: &PathResolutionOptions, ) -> VfsResult<(VfsEntryRef, Arc<MountPoint>)>

fn resolve_component_no_symlink( &self, entry: VfsEntryRef, component: &str, ) -> VfsResult<VfsEntryRef>

Resolve a single path component without following symlinks

pub fn parse_path(&self, path: &str) -> Vec<String>

Parse a path into components

fn get_mount_path(&self, mount: &Arc<MountPoint>) -> String

Get the full path of a mount point

fn resolve_component( &self, entry: VfsEntryRef, component: &str, ) -> VfsResult<VfsEntryRef>

Resolve a single path component within a VFS entry

fn resolve_component_with_depth( &self, entry: VfsEntryRef, component: &str, symlink_depth: u32, ) -> VfsResult<VfsEntryRef>

Resolve a single path component with symlink depth tracking

fn resolve_symlink_target( &self, base_entry: &VfsEntryRef, target: &str, ) -> VfsResult<VfsEntryRef>

Resolve a symbolic link target

fn resolve_symlink_target_with_depth( &self, base_entry: &VfsEntryRef, target: &str, symlink_depth: u32, ) -> VfsResult<VfsEntryRef>

Resolve a symbolic link target with depth tracking

Trait Implementations

impl Debug for MountTree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
