Struct procfs::process::MountInfo

pub struct MountInfo {
    pub mnt_id: i32,
    pub pid: i32,
    pub majmin: String,
    pub root: String,
    pub mount_point: PathBuf,

}

Information about a specific mount in a process’s mount namespace.

This data is taken from the /proc/[pid]/mountinfo file.

For an example, see the mountinfo.rs example in the source repo.

Fields

mnt_id: i32

Mount ID. A unique ID for the mount (but may be reused after unmount)

pid: i32

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

If the parent mount point lies outside the process’s root directory, the ID shown here won’t have a corresponding record in mountinfo whose mount ID matches this parent mount ID (because mount points that lie outside the process’s root directory are not shown in mountinfo). As a special case of this point, the process’s root mount point may have a parent mount (for the initramfs filesystem) that lies outside the process’s root directory, and an entry for that mount point will not appear in mountinfo.

majmin: String

The value of st_dev for files on this filesystem

root: String

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

mount_point: PathBuf

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

mount_options: HashMap<String, Option<String>>

Per-mount options

opt_fields: Vec<MountOptFields>

Optional fields

fs_type: String

Filesystem type

mount_source: Option<String>

Mount source

super_options: HashMap<String, Option<String>>

Per-superblock options.
