Enum InitStage 

#[non_exhaustive]
pub enum InitStage {
    Core,
    Servers,
    Scene,
    Editor,
    MainLoop,
}

Extended initialization stage that includes both initialization levels and the main loop.

This enum extends InitLevel with a MainLoop variant, representing the fully initialized state of Godot after all initialization levels have been loaded and before any deinitialization begins.

During initialization, stages are loaded in order: Core → Servers → Scene → Editor (if in editor) → MainLoop.
During deinitialization, stages are unloaded in reverse order.

See also:

• InitLevel: only levels, without MainLoop.
• ExtensionLibrary::on_stage_init()
• ExtensionLibrary::on_stage_deinit()
• ExtensionLibrary::on_main_loop_frame()

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Core

First level loaded by Godot. Builtin types are available, classes are not.

Servers

Second level loaded by Godot. Only server classes and builtins are available.

Scene

Third level loaded by Godot. Most classes are available.

Editor

Fourth level loaded by Godot, only in the editor. All classes are available.

MainLoop

Available on since_api=4.5 only.

The main loop stage, representing the fully initialized state of Godot.

This variant is only available in Godot 4.5+. In earlier versions, it will never be passed to callbacks.

Implementations

impl InitStage

pub fn try_to_level(self) -> Option<InitLevel>

Try to convert this initialization stage to an initialization level.

Returns None for InitStage::MainLoop, as it doesn’t correspond to a Godot initialization level.

Trait Implementations

impl Clone for InitStage

fn clone(&self) -> InitStage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitStage

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

Formats the value using the given formatter.

impl Hash for InitStage

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 InitStage

fn cmp(&self, other: &InitStage) -> 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 InitStage

fn eq(&self, other: &InitStage) -> 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 InitStage

fn partial_cmp(&self, other: &InitStage) -> 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.
