Struct HistoryConfig 

pub struct HistoryConfig {
    pub enabled: bool,
    pub max_age_days: u32,
    pub max_rows: u64,
    pub path: Option<String>,
}

Configuration for the persistent query-history store at ~/.local/share/ferrule/history.db (R4 / #4).

Default-on. The FERRULE_NO_HISTORY env var kills recording for a single invocation without touching this config.

Fields

enabled: bool

max_age_days: u32

Open-loop retention: rows older than this many days are pruned opportunistically on the next record() call. 0 disables age-based pruning.

max_rows: u64

Open-loop retention: cap on the total row count. 0 disables count-based pruning. Pruning, when triggered, deletes the oldest rows first.

path: Option<String>

Path to the SQLite store. When None, defaults to <XDG_DATA_HOME>/ferrule/history.db (Linux/macOS) or the platform equivalent via dirs::data_local_dir().
