Struct Mounts 

pub struct Mounts { /* private fields */ }

The mount table, parsed once; resolving paths against it is string work, so a whole listing needs one read.

Implementations

impl Mounts

pub fn current() -> Self

Read the current mount table. An unreadable one yields an empty table, which reports everything as unknown rather than as wrong.

pub fn cached() -> Arc<Self>

The mount table as of at most MOUNTS_TTL ago, shared: reading /proc is most of an answer’s cost, and five thousand rows asked it per row per frame.

pub fn parse(mountinfo: &str) -> Self

pub fn fstype_for(&self, path: &Path) -> Option<&str>

The filesystem covering path: the deepest mount, and at one point the last listed (a later mount shadows an earlier one, as NFS automounted over its autofs entry).

pub fn mount_point_for(&self, path: &Path) -> PathBuf

Where the filesystem covering path is mounted; empty when nothing covers it.

pub fn describe(&self, path: &Path) -> Source

How path is reached.

pub fn is_network(&self, path: &Path) -> bool

pub fn could_block(&self, path: &Path) -> bool

Whether a call on path can hang: a network filesystem, or any FUSE one, whose answers come from a process that may be waiting on a network or on nothing at all. For what stays off the key thread; a local FUSE layer (mergerfs, gocryptfs) is listed, measured and previewed as the disk it is.

impl Default for Mounts

fn default() -> Self

Returns the “default value” for a type.
