Enum gdk4::DragCancelReason

#[non_exhaustive]
pub enum DragCancelReason {
    NoTarget,
    UserCancelled,
    Error,
}

Used in Drag to the reason of a cancelled DND operation.

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.

NoTarget

There is no suitable drop target.

UserCancelled

Drag cancelled by the user

Error

Unspecified error.

impl Ord for DragCancelReason

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.
