Member Data Documentation

compression

const Setting<std::string> nix::BinaryCacheStoreConfig::compression

Initial value:

{this, "xz", "compression",
        "NAR compression method (`xz`, `bzip2`, `gzip`, `zstd`, or `none`)."}

compressionLevel

const Setting<int> nix::BinaryCacheStoreConfig::compressionLevel

Initial value:

{this, -1, "compression-level",
        R"(
          The *preset level* to be used when compressing NARs.
          The meaning and accepted values depend on the compression method selected.
          `-1` specifies that the default compression level should be used.
        )"}

localNarCache

const Setting<Path> nix::BinaryCacheStoreConfig::localNarCache

Initial value:

{this, "", "local-nar-cache",
        "Path to a local cache of NARs fetched from this binary cache, used by commands such as `nix store cat`."}

parallelCompression

const Setting<bool> nix::BinaryCacheStoreConfig::parallelCompression

Initial value:

{this, false, "parallel-compression",
        "Enable multi-threaded compression of NARs. This is currently only available for `xz` and `zstd`."}

secretKeyFile

const Setting<Path> nix::BinaryCacheStoreConfig::secretKeyFile

Initial value:

{this, "", "secret-key",
        "Path to the secret key used to sign the binary cache."}

writeDebugInfo

const Setting<bool> nix::BinaryCacheStoreConfig::writeDebugInfo

Initial value:

{this, false, "index-debug-info",
        R"(
          Whether to index DWARF debug info files by build ID. This allows [`dwarffs`](https://github.com/edolstra/dwarffs) to
          fetch debug info on demand
        )"}

writeNARListing

const Setting<bool> nix::BinaryCacheStoreConfig::writeNARListing

Initial value:

{this, false, "write-nar-listing",
        "Whether to write a JSON file that lists the files in each NAR."}
