RebuildStateMachine

Struct RebuildStateMachine 

Source
pub struct RebuildStateMachine {
    pub in_progress: bool,
    pub started_at: Option<Instant>,
}
Expand description

State-machine: решение о реакции на результат фоновой сборки.

Вынесена отдельно от потоков, чтобы юнит-тестировать без реального cargo. Все методы чистые: принимают текущий статус и возвращают новый (без side effects кроме лога в mark_rebuild_failure, который нужен по ТЗ 5.3).

Fields§

§in_progress: bool

true, если сейчас идёт фоновая сборка.

§started_at: Option<Instant>

Момент запуска последней активной сборки (для лога «took N s»).

Implementations§

Source§

impl RebuildStateMachine

Source

pub fn start(&mut self)

Запускаем новую фоновую сборку. Если старая ещё идёт — её нужно убить (вызывается снаружи; здесь только поднимаем флаг + таймер).

Source

pub fn poll_outcome(&mut self, exit_code: i32) -> RebuildOutcome

Обработать результат завершившейся сборки. Возвращает RebuildOutcome, по которому main-loop решает, делать ли swap.

Source

pub fn reset(&mut self)

Сброс после завершённого цикла (для теста).
