Struct CacheConfig 

pub struct CacheConfig {
    pub listen: String,
    pub backend: BackendConfig,
    pub signing_key: Option<PathBuf>,
    pub priority: u32,
    pub want_mass_query: bool,
    pub store_dir: String,
    pub require_sigs: bool,
}

Top-level cache configuration.

Fields

listen: String

Network address to listen on.

backend: BackendConfig

Storage backend configuration.

signing_key: Option<PathBuf>

Path to the ed25519 signing secret key file.

In production this path is a cofre/ESO-materialized Kubernetes Secret mount, never a plaintext literal. When set, the daemon signs every ingested narinfo (see serve).

priority: u32

Cache priority (lower = preferred). Reported in nix-cache-info.

want_mass_query: bool

Whether to want mass query (narinfo pipelining).

store_dir: String

The Nix store directory (almost always /nix/store).

require_sigs: bool

Whether this cache’s consumers should require a valid signature.

This is a serving-side advertisement of the fail-closed posture: a signing cache SHOULD publish require_sigs = true so operators know the served paths are signed and consumers must verify. It does not by itself change what the daemon serves (signing is driven by signing_key); it is the typed knob a consuming config reads to know the cache is trustworthy fail-closed. Defaults to false to preserve legacy behavior for caches that have not yet been given a key.
