Enum Outcome 

pub enum Outcome {
    Committed(Tier),
    Local,
    Stale {
        lag_ops: usize,
    },
    Unavailable(UnavailableReason),
}

The consistency a read or write actually achieved.

Variants

Committed(Tier)

The op was committed at this tier (a strong commit, or a causal/convergent read that is up to date with what the session has observed).

Local

Written locally and offline-durable, but not yet propagated to peers.

Stale

Served from a replica that is behind the session’s frontier by lag_ops operations — honestly stale, not silently so.

Fields

lag_ops: usize

Unavailable(UnavailableReason)

A strong op could not be served and was not committed divergently.

Implementations

impl Outcome

pub fn is_committed(&self) -> bool

Whether the op committed at some tier.

pub fn is_available(&self) -> bool

Whether the op was served at all (anything but Unavailable).

pub fn tier(&self) -> Option<Tier>

The tier committed at, if any.
