Enum IsUsed 

pub enum IsUsed {
    Unused,
    Used,
}

Return type of event-handling methods

This type is convertible to/from bool and supports the expected bit-wise OR operator (a | b, *a |= b).

The type also implements negation with output type bool, thus allowing if is_used.into() { ... } and if !is_used { ... }. An implementation of Deref would be preferred, but the trait can only output a reference.

Variants

Unused

Event was unused

Unused events may be used by a parent/ancestor widget or passed to another handler until used.

Used

Event is used, no other result

Trait Implementations

impl BitOr for IsUsed

type Output = IsUsed

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for IsUsed

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for IsUsed

fn clone(&self) -> IsUsed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IsUsed

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

Formats the value using the given formatter.

impl From<IsUsed> for bool

fn from(is_used: IsUsed) -> bool

Converts to this type from the input type.

impl From<bool> for IsUsed

fn from(is_used: bool) -> Self

Converts to this type from the input type.

impl Hash for IsUsed

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 Not for IsUsed

type Output = bool

The resulting type after applying the ! operator.

fn not(self) -> bool

Performs the unary ! operation.

impl PartialEq for IsUsed

fn eq(&self, other: &IsUsed) -> 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.
