Struct bevy_app::PreUpdate

pub struct PreUpdate;

The schedule that contains logic that must run before Update. For example, a system that reads raw keyboard input OS events into an Events resource. This enables systems in Update to consume the events from the Events resource without actually knowing about (or taking a direct scheduler dependency on) the “os-level keyboard event sytsem”.

PreUpdate exists to do “engine/plugin preparation work” that ensures the APIs consumed in Update are “ready”. PreUpdate abstracts out “pre work implementation details”.

This is run by the Main schedule.

Trait Implementations

impl AsRef<dyn ScheduleLabel> for PreUpdatewhere Self: 'static + Send + Sync + Clone + Eq + Debug + Hash,

fn as_ref(&self) -> &dyn ScheduleLabel

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PreUpdate

fn clone(&self) -> PreUpdate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PreUpdate

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

Formats the value using the given formatter.

impl Hash for PreUpdate

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 PartialEq<PreUpdate> for PreUpdate

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

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

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.

impl ScheduleLabel for PreUpdatewhere Self: 'static + Send + Sync + Clone + Eq + Debug + Hash,

fn dyn_clone(&self) -> Box<dyn ScheduleLabel>

Clones this ScheduleLabel

fn as_dyn_eq(&self) -> &dyn DynEq

Casts this value to a form where it can be compared with other type-erased values.

fn dyn_hash(&self, state: &mut dyn Hasher)

Feeds this value into the given Hasher.

fn inner_type_id(&self) -> TypeId

Return’s the TypeId of this label, or the the ID of the wrappped label type for Box<dyn ScheduleLabel >
