Enum Durability 

pub enum Durability {
    ProcessLocal,
    CrashDurable,
}

What a store guarantees about state after the writing process ends.

Variants

ProcessLocal

State lives only in this process. Replay and resume work while it runs; a crash loses everything the store held, and another process cannot resume its sessions.

CrashDurable

State is written to a backing store before the write is acknowledged, so another process can reconstruct a session after loss.

Implementations

impl Durability

pub fn survives_process_loss(&self) -> bool

Whether state written to this store outlives the process that wrote it.

Callers that require durability should check this at startup rather than infer it from the presence of checkpointing.
