Enum gtk::MenuDirectionType

#[non_exhaustive]
pub enum MenuDirectionType {
    Parent,
    Child,
    Next,
    Prev,
    // some variants omitted
}

An enumeration representing directional movements within a menu.

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.

Parent

To the parent menu shell

Child

To the submenu, if any, associated with the item

Next

To the next menu item

Prev

To the previous menu item

impl Ord for MenuDirectionType

fn cmp(&self, other: &MenuDirectionType) -> 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>,

impl PartialEq<MenuDirectionType> for MenuDirectionType

fn eq(&self, other: &MenuDirectionType) -> 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 returns an ordering between self and other values if one exists.

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

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
