Struct CacheConfig 

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

Result-cache configuration (R5 / #5). Default-on with a conservative 5-minute TTL. Backed by a separate results.db (NOT the history store — cache eviction churns faster than telemetry retention).

The FERRULE_NO_CACHE env var kills the cache for a single invocation without touching this config. Passing --cache 0 to ferrule query also bypasses the cache for that one run.

Fields

enabled: bool

default_ttl: String

Default TTL applied to inserts when the caller didn’t pass an explicit --cache DURATION. Same s/m/h/d suffix grammar as --since. "0" (the literal string) disables insertion without disabling lookup of existing entries.

max_age_days: u32

Open-loop retention: rows older than this many days are pruned opportunistically on the next prune() pass. 0 disables.

max_rows: u64

Open-loop retention: cap on total rows. Oldest rows are discarded first. 0 disables.

path: Option<String>

Path to the SQLite store. When None, defaults to <XDG_DATA_HOME>/ferrule/results.db via dirs::data_local_dir().
