Struct HistoryResult 

Source 
pub struct HistoryResult<T> {
    pub items: Vec<T>,
    pub total_commits: u64,
}
Expand description

Result wrapper for history queries. Carries the event list and the total number of WAL commits visible in the current horizon window.

Valid commit indices for was_linked are 0..total_commits. Any index >= total_commits is outside the horizon and was_linked will return CommitOutOfRange.

Fields§

§items: Vec<T>§total_commits: u64

Exclusive upper bound for valid commit indices (frames.len()). The horizon window is [0, total_commits).
