Struct FsEntry

pub struct FsEntry {
    pub device_spec: String,
    pub mountpoint: Option<String>,
    pub fs_type: String,
    pub options: Vec<String>,
    pub dump_freq: u8,
    pub pass: FsckOrder,
}

Fields

device_spec: String

The device spec for mounting the filesystem.

Can be a device path, or some kind of filter to get the device, i.e LABEL=ROOT or UUID=1234-5678

Examples:

• /dev/sda1
• LABEL=ROOT
• UUID=1234-5678
• PARTUUID=1234-5678
• PARTLABEL=ROOT
• PARTUUID=1234-5678
• PARTLABEL=ROOT

mountpoint: Option<String>

The mountpoint for the filesystem. Specifies where the filesystem should be mounted.

Doesn’t actually need to be a real mountpoint, but most of the time it will be.

Is an optional field, a None value will serialize into none.

Examples:

• /
• /boot
• none (for no mountpoint, used for swap or similar filesystems)
• /home

fs_type: String

The filesystem type for the filesystem.

Examples:

• ext4
• btrfs
• vfat
• …

options: Vec<String>

Mount options for the filesystem. Is a comma-separated list of options.

This type returns a vector of strings, as there can be multiple options. They will be serialized into a comma-separated list.

dump_freq: u8

The dump frequency for the filesystem.

This is a number that specifies how often the filesystem should be backed up.

pass: FsckOrder

The pass number for the filesystem.

Determines when the filesystem health should be checked using fsck.
