Enum ExecutionPhase 

pub enum ExecutionPhase {
    Boot,
    Menu,
    Simulation,
    Background,
}

The high-level workload state of the engine.

Variants

Boot

Engine is starting up and loading assets.

Menu

User is in an interactive menu.

Simulation

Full simulation is running (gameplay).

Background

Application is minimized or lost focus.

Implementations

impl ExecutionPhase

pub fn can_transition_to(&self, target: ExecutionPhase) -> bool

Returns true if the transition from self to target is valid.

Valid transitions:

• Boot → Menu, Simulation
• Menu → Simulation, Background
• Simulation → Menu, Background
• Background → Menu, Simulation

pub fn name(&self) -> &'static str

Returns a human-readable name for this phase.

pub fn from_name(name: &str) -> Option<Self>

Parses a phase from a string (case-insensitive).

Trait Implementations

impl Clone for ExecutionPhase

fn clone(&self) -> ExecutionPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionPhase

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

Formats the value using the given formatter.

impl Default for ExecutionPhase

fn default() -> ExecutionPhase

Returns the “default value” for a type.

impl PartialEq for ExecutionPhase

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