Struct ConditionalSetOutcome 

#[non_exhaustive]
pub struct ConditionalSetOutcome {
    pub matched: bool,
    pub previous_total: u64,
    pub current_total: u64,
}

Result of a conditional total update.

Distinguishes comparator misses from successful updates that leave total unchanged.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

matched: bool

Whether comparator matched and update semantics were applied.

previous_total: u64

Live total observed before conditional update.

current_total: u64

Live total after operation, or unchanged total when comparator missed.
