Struct EventOutcome 

pub struct EventOutcome<A> {
    pub actions: Vec<A>,
    pub needs_render: bool,
}

Result of mapping an event into actions plus an optional render hint.

Fields

actions: Vec<A>

Actions to enqueue.

needs_render: bool

Whether to force a re-render.

Implementations

impl<A> EventOutcome<A>

pub fn ignored() -> Self

No actions and no render.

pub fn needs_render() -> Self

No actions, but request a render.

pub fn action(action: A) -> Self

Wrap a single action.

pub fn actions<I>(actions: I) -> Self

where I: IntoIterator<Item = A>,

Wrap multiple actions.

pub fn with_render(self) -> Self

Mark that a render is needed.

Trait Implementations

impl<A: Clone> Clone for EventOutcome<A>

fn clone(&self) -> EventOutcome<A>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<A: Debug> Debug for EventOutcome<A>

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

Formats the value using the given formatter.

impl<A> Default for EventOutcome<A>

fn default() -> Self

Returns the “default value” for a type.

impl<A> From<A> for EventOutcome<A>

fn from(action: A) -> Self

Converts to this type from the input type.

impl<A> From<Option<A>> for EventOutcome<A>

fn from(action: Option<A>) -> Self

Converts to this type from the input type.

impl<A> From<Vec<A>> for EventOutcome<A>

fn from(actions: Vec<A>) -> Self

Converts to this type from the input type.

impl<A: PartialEq> PartialEq for EventOutcome<A>

fn eq(&self, other: &EventOutcome<A>) -> 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.
