Enum MountUuid 

pub enum MountUuid {
    Text(String),
    Absent,
    Unknown,
}

What: What findmnt would print for the UUID column of a path, as far as this module can prove it without starting findmnt. Why: The caller records an identity from Text, skips findmnt for Absent, and spawns findmnt for Unknown.

In TS you’d write (pseudocode):

type MountUuid = { kind: 'text'; text: string } | { kind: 'absent' } | { kind: 'unknown' };

Variants

Text(String)

findmnt prints exactly this text and a newline.

Absent

findmnt prints an empty line: the mounted source is a pseudo filesystem with no UUID.

Unknown

This module cannot prove what findmnt prints.
