Enum Subject 

pub enum Subject {
    Command(String),
    File {
        path: String,
        volume_serial: Option<u32>,
    },
    Folder {
        path: String,
        volume_serial: Option<u32>,
    },
    Device {
        id: String,
        volume_serial: Option<u32>,
    },
    Query(String),
}

The thing an Action was performed on.

Variants

Command(String)

A shell command or program invocation.

File

A file path, carrying the volume serial of the volume it lives on when the source knows it (LNK VolumeID). The serial is the join key to a Subject::Device with the same volume serial (see device_file_volume_joins).

Fields

path: String

The file path.

volume_serial: Option<u32>

NTFS/FAT volume serial of the file’s volume, when known.

Folder

A folder path, carrying the volume serial of the volume it lives on when the source knows it (shellbag / LNK directory target).

Fields

path: String

The folder path.

volume_serial: Option<u32>

NTFS/FAT volume serial of the folder’s volume, when known.

Device

An external device, with its volume serial kept distinct so an LNK / shellbag Subject::File carrying the same NTFS/FAT volume serial can be joined to it (see device_file_volume_joins).

Fields

id: String

Device instance id (the stable primary key).

volume_serial: Option<u32>

NTFS/FAT volume serial of the device’s volume, when known.

Query(String)

A search / lookup query.

Implementations

impl Subject

pub fn file(path: impl Into<String>) -> Self

A file path with no known volume serial.

pub fn folder(path: impl Into<String>) -> Self

A folder path with no known volume serial.

Trait Implementations

impl Clone for Subject

fn clone(&self) -> Subject

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Subject

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Subject

impl Hash for Subject

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Subject

fn eq(&self, other: &Subject) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
