RunCycle

devela::zall_::_run

Struct RunCycle 

Source 
pub struct RunCycle { /* private fields */ }
Expand description

⬡ Manages run phases and guards phase transitions.

📍 run/cycle

RunCycle tracks the high-level lifecycle of a running system.

It is intentionally small:

  • it does not advance time,
  • it does not schedule work,
  • it does not own runtime services.

It only answers what phase the run is in and whether a transition is valid.

Implementations§

Source§

impl RunCycle

Source

pub const fn new() -> Self

Creates a new cycle in the Init phase.

Source

pub const fn phase(self) -> RunPhase

Source

pub const fn is_paused(self) -> bool

Returns true if the run is in the Paused phase.

Source

pub const fn is_stopped(self) -> bool

Returns true if the run is in the Stopped phase.

Source

pub const fn can_advance(self) -> bool

Source

pub const fn can_transition(self, next: RunPhase) -> bool
