Struct SetMemDescriptionOutcome 

pub struct SetMemDescriptionOutcome {
    pub mem: String,
    pub old_description: Option<String>,
    pub new_description: Option<String>,
    pub warnings: Vec<WarningHint>,
}

Result of Engine::set_mem_description. Carries the (mem, old_description, new_description) triple so callers can surface the change without an extra read.

Fields

mem: String

old_description: Option<String>

Previous description. None when the mem config carried no description before this call (the common case — mem creation seeds none).

new_description: Option<String>

The description now persisted; None when the call cleared it.

warnings: Vec<WarningHint>

Concurrent-drift warnings detected at the pre-write probe. Empty on the happy path.
