pub fn install_key(
keys_path: &Path,
tenant: &str,
lane: LaneClass,
rate_limit: Option<usize>,
key: &str,
) -> Result<String, String>Expand description
Install an already-generated key into a ring. This is the fleet fan-out primitive: one control-plane key can be installed byte-identically on every serving origin without making any serving host the authority for the others. Replaying the exact same entry is idempotent; a prefix collision with different material or policy fails closed.
