Struct SetMemSyncStateOutcome 

pub struct SetMemSyncStateOutcome {
    pub mem: String,
    pub key: String,
    pub previous: Option<String>,
    pub removed: bool,
    pub warnings: Vec<WarningHint>,
}

Result of Engine::set_mem_sync_state. Carries the (mem, key, previous-token) triple so callers (CLI, MCP) can surface the change without an extra read. The token values are opaque to the engine — see MemConfig::sync_state.

Fields

mem: String

key: String

The sync-state key that was set or cleared (opaque; the ingest layer keys per (ingest, facet)).

previous: Option<String>

Previous token under key, None when the key was unset before this call. Lets callers report set-vs-overwrite without a read.

removed: bool

True when an empty token cleared an existing key. false for a set/overwrite and for a clear of an already-absent key (a no-op).

warnings: Vec<WarningHint>

Concurrent-drift warnings detected at the pre-write probe — e.g. MemReloaded when a sibling engine committed between this engine’s last snapshot and the write. Empty on the happy path.
