Enum Stage 

pub enum Stage {
    PreUpdate,
    Update,
    PostUpdate,
    Runtime,
}

Execution stages for systems in a frame

Systems are grouped by stage and run in this order: PreUpdate -> Update -> PostUpdate -> Runtime

Variants

PreUpdate

Runs before game logic. Use for input handling and preparation

Update

Main game logic. Most user systems should be here

PostUpdate

Runs after game logic. Use for cleanup or derived updates

Runtime

Internal engine systems (e.g. scene management)`

Implementations

impl Stage

pub const ORDER: [Stage; 4]

Order of stages

Trait Implementations

impl Clone for Stage

fn clone(&self) -> Stage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stage

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

Formats the value using the given formatter.

impl Hash for Stage

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 for Stage

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