Function read_strongly_consistent_and_apply_effects 

pub async fn read_strongly_consistent_and_apply_effects<T, F>(
    op: OperationVc<T>,
    get_effects: F,
) -> Result<ReadRef<T>>
where
    T: VcValueType,
    F: Fn(&<<T as VcValueType>::Read as VcRead<T>>::Target) -> &Effects,

Strongly-consistent read of op, then apply its effects, retrying the whole read+apply on EffectsError::Retry.

get_effects extracts the Effects from the read value (for a wrapper struct this is |v| &v.effects; for an OperationVc<Effects> it is |e| e).

On EffectsError::Retry the producing operation has already been invalidated by Effects::apply, so the next read_strongly_consistent re-runs the producer and yields a fresh Effects whose capture() re-materializes content. Retries are bounded to avoid livelock when two producers perpetually stomp the same key; after the first retry a warning is logged on each subsequent attempt, and on exhaustion the last Retry surfaces as an error.

This is one of two public entry points for applying effects (see also [read_strongly_consistent_and_apply_effects_with]) — Effects::apply is private so the retry contract cannot be bypassed.
