Enum gtk::DragResult

#[non_exhaustive]
pub enum DragResult {
    Success,
    NoTarget,
    UserCancelled,
    TimeoutExpired,
    GrabBroken,
    Error,
    // some variants omitted
}

Gives an indication why a drag operation failed. The value can by obtained by connecting to the signal::Widget::drag-failed signal.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Success

The drag operation was successful.

NoTarget

No suitable drag target.

UserCancelled

The user cancelled the drag operation.

TimeoutExpired

The drag operation timed out.

GrabBroken

The pointer or keyboard grab used for the drag operation was broken.

Error

The drag operation failed due to some unspecified error.

impl Clone for DragResult

fn clone(&self) -> DragResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DragResult

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

Formats the value using the given formatter.

impl Display for DragResult

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for DragResult

type Checker = GenericValueTypeChecker<DragResult>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl Hash for DragResult

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,

Feeds a slice of this type into the given Hasher.

impl Ord for DragResult

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<DragResult> for DragResult

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

This method tests for self and other values to be equal, and is used by ==.

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for DragResult

fn to_value(&self) -> Value

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for DragResult

type Type = DragResult

Type to get the Type from.
