Struct Mount 

pub struct Mount {
    pub device: String,
    pub mountpoint: PathBuf,
    pub fstype: String,
    pub mountopts: String,
}

Represent a mountpoint

Fields

device: String

The device name (either a path or something like zram0)

mountpoint: PathBuf

The target directory it has been mounted to

fstype: String

Type of filesystem

mountopts: String

Mount options

Implementations

impl Mount

pub fn list() -> Result<impl Iterator<Item = Self>, LsblkError>

List out all mountpoints and populate all fields.

Errors

Since this function depends on the existence of /proc/mounts, failures to open the file will cause crate::LsblkError::ReadFile.

Caveats

If for some reason /proc/mounts is not formatted properly, the iterator will skip those lines. This includes

• trailing whitespace
• fs_freq and fs_passno (which are the last 2 fields on each line) not set to 0
• not separating the fields with only 1 single space (' ')

For more information, visit proc_pid_mounts(5).

Examples

for m in lsblk::Mount::list()? {
    println!("{} mounted at {}", m.device, m.mountpoint.display());
}

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

List out the mounting options (fs_mntopts).

This returns an iterator of (key, optional value).

Examples

let mountopts = String::from("rw,relatime,compress=zstd:1,ssd,discard=async,subvol=/root");
let m = lsblk::Mount {
    mountopts,
    ..lsblk::Mount::default()
};
let mut it = m.iter_mountopts();
assert_eq!(it.next(), Some(("rw", None)));
assert_eq!(it.next(), Some(("relatime", None)));
assert_eq!(it.next(), Some(("compress", Some("zstd:1"))));
assert_eq!(it.next(), Some(("ssd", None)));
assert_eq!(it.next(), Some(("discard", Some("async"))));
assert_eq!(it.next(), Some(("subvol", Some("/root"))));
assert_eq!(it.next(), None);
