Fields

mounts: SpinLock<BTreeMap<String, Vec<Arc<MountPoint>>>>

挂载路径 -> 挂载点栈（最后一个是当前可见的）

Implementations

impl MountTable

pub const fn new() -> Self

创建新的挂载表

pub fn mount( &self, fs: Arc<dyn FileSystem>, path: &str, flags: MountFlags, device: Option<String>, ) -> Result<(), FsError>

挂载文件系统

pub fn umount(&self, path: &str) -> Result<(), FsError>

卸载文件系统

pub fn find_mount(&self, path: &str) -> Option<Arc<MountPoint>>

查找给定路径的挂载点

返回最长匹配的挂载点（栈顶）

pub fn root_mount(&self) -> Option<Arc<MountPoint>>

获取根挂载点

pub fn list_mounts(&self) -> Vec<(String, String)>

列出所有挂载点（用于调试）

pub fn list_all(&self) -> BTreeMap<String, Arc<MountPoint>>
