Enum gdk::PropertyState

#[non_exhaustive]pub enum PropertyState {
    NewValue,
    Delete,
    // some variants omitted
}

Specifies the type of a property change for a EventProperty.

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.

NewValue

the property value was changed.

Delete

the property was deleted.

impl Ord for PropertyState

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<PropertyState> for PropertyState

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

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

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

This method tests for !=.

impl PartialOrd<PropertyState> for PropertyState

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

This method returns an ordering between self and other values if one exists.

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

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

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

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

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

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

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