Struct MountInfo 

pub struct MountInfo {
    pub id: Option<MountId>,
    pub parent: Option<MountId>,
    pub dev: DeviceId,
    pub root: PathBuf,
    pub mount_point: PathBuf,
    pub options: Vec<MountOption>,
    pub fs: String,
    pub fs_type: String,
    pub bound: bool,
}

A mount point as described in /proc/self/mountinfo

Fields

id: Option<MountId>

parent: Option<MountId>

dev: DeviceId

root: PathBuf

mount_point: PathBuf

options: Vec<MountOption>

fs: String

fs_type: String

bound: bool

whether it’s a bound mount (usually mirroring part of another device)

Implementations

impl MountInfo

pub fn dm_name(&self) -> Option<&str>

return <name> when the path is /dev/mapper/<name>

pub fn fs_name(&self) -> Option<&str>

return the last token of the fs path

pub fn is_remote(&self) -> bool

tell whether the mount looks remote

Heuristics copied from https://github.com/coreutils/gnulib/blob/master/lib/mountlist.c

pub fn options_string(&self) -> String

return a string like “rw,noatime,compress=zstd:3,space_cache=v2,subvolid=256” (as in /proc/mountinfo)

Some options may be skipped as they’re less relevant (but you may still find them in the options vec)

pub fn has_option(&self, name: &str) -> bool

tell whether the option (eg “compress”, “rw”, “noatime”) is present among options

pub fn option_value(&self, name: &str) -> Option<&str>

return the value of the mountoption, or None
