Struct MountPoint

pub struct MountPoint<'a> { /* private fields */ }

Implementations

impl<'a> MountPoint<'a>

pub fn values(&self) -> impl Iterator<Item = &'a str>

Returns every value separated by a space.

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

A unique ID for the mount (may be reused after umount).

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

The ID of the parent mount (or of self for the root of this mount namespace’s mount tree).

pub fn major_minor(&self) -> Option<&'a str>

major:minor: the value of st_dev for files on this filesystem.

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

Gets the major value.

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

Gets the minor value.

pub fn root(&self) -> Option<&'a str>

the pathname of the directory in the filesystem which forms the root of this mount.

pub fn mount_point(&self) -> Option<&'a str>

The pathname of the mount point relative to the process’s root directory.

		format!("{:.1}", stat.total()?),
		format!("{:.1}", stat.available()?),
		format!("{:.1}", stat.used()?),
		point.mount_point()?
	);

	Some(())
}

pub fn mount_options(&self) -> Option<&'a str>

Per-mount options.

pub fn optional_fields( &self, ) -> impl Iterator<Item = (&'a str, Option<&'a str>)>

Currently, the possible optional fields are shared, master, propagate_from, and unbindable.

pub fn filesystem_type(&self) -> Option<&'a str>

The filesystem type in the form “type[.subtype]”.

pub fn mount_source(&self) -> Option<&'a str>

Filesystem-specific information.
df command uses this information as Filesystem.

Trait Implementations

impl<'a> Clone for MountPoint<'a>

fn clone(&self) -> MountPoint<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for MountPoint<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for MountPoint<'a>

fn eq(&self, other: &MountPoint<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
