Struct CoreMenuCallback 

#[repr(C)]
pub struct CoreMenuCallback {
    pub refany: RefAny,
    pub callback: CoreCallback,
}

Menu callback using usize placeholder for function pointer.

This type is used in azul-core to represent menu item callbacks without creating circular dependencies with azul-layout. The actual function pointer is stored as a usize and converted via unsafe code in azul-layout.

Fields

refany: RefAny

User data passed to the callback when the menu item is clicked

callback: CoreCallback

Callback function pointer stored as usize (converted to real fn pointer in azul-layout)

Trait Implementations

impl Clone for CoreMenuCallback

fn clone(&self) -> CoreMenuCallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreMenuCallback

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

Formats the value using the given formatter.

impl Hash for CoreMenuCallback

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CoreMenuCallback

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

This method returns an Ordering between self and other.

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 PartialEq for CoreMenuCallback

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

Tests for self and other values to be equal, and is used by ==.

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 PartialOrd for CoreMenuCallback

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

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

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.
