Struct Drive

pub struct Drive { /* private fields */ }

GDrive represents a piece of hardware connected to the machine. It’s generally only created for removable hardware or hardware with removable media. For example, an optical disc drive, or a USB flash drive.

GDrive is a container class for Volume objects that stem from the same piece of media. As such, GDrive abstracts a drive with (or without) removable media and provides operations for querying whether media is available, determining whether media change is automatically detected and ejecting the media.

If the GDrive reports that media isn’t automatically detected, one can poll for media; typically one should not do this periodically as a poll for media operation is potentially expensive and may spin up the drive creating noise.

GDrive supports starting and stopping drives with authentication support for the former. This can be used to support a diverse set of use cases including connecting/disconnecting iSCSI devices, powering down external disk enclosures and starting/stopping multi-disk devices such as RAID devices. Note that the actual semantics and side-effects of starting/stopping a GDrive may vary according to implementation. To choose the correct verbs in e.g. a file manager, use DriveExt::start_stop_type().

For porting from GnomeVFS note that there is no equivalent of GDrive in that API.

Signals

changed

Emitted when the drive’s state has changed.

disconnected

This signal is emitted when the #GDrive have been disconnected. If the recipient is holding references to the object they should release them so the object can be finalized.

eject-button

Emitted when the physical eject button (if any) of a drive has been pressed.

stop-button

Emitted when the physical stop button (if any) of a drive has been pressed.

Implements

DriveExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl Drive

pub const NONE: Option<&'static Drive> = None

Trait Implementations

impl Clone for Drive

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for Drive

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

Formats the value using the given formatter.

impl HasParamSpec for Drive

type ParamSpec = ParamSpecObject

type SetValue = Drive

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, Drive>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Drive

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

where H: Hasher,

Hashes the memory address of this object.

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 Ord for Drive

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<OT: ObjectType> PartialEq<OT> for Drive

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

impl<OT: ObjectType> PartialOrd<OT> for Drive

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for Drive

fn static_type() -> Type

Returns the type identifier of Self.
