Fields§

§flags: Flags§store_path: StorePathRef<'a>

Store path described by this NarInfo

§nar_hash: [u8; 32]

SHA-256 digest of the NAR file

§nar_size: u64

Size of the NAR file in bytes

§references: Vec<StorePathRef<'a>>

Store paths known to be referenced by the contents

§signatures: Vec<Signature<'a>>

Ed25519 signature over the path fingerprint

§ca: Option<CAHash>

Content address (for content-defined paths)

§system: Option<&'a str>

Nix system triple of NarInfo::deriver

§deriver: Option<StorePathRef<'a>>

Store path of the derivation that produced this. The last .drv suffix is stripped.

§url: &'a str

Relative URL of the compressed NAR file

§compression: Option<&'a str>

Compression method of the NAR file None means Compression: none.

Nix interprets a missing Compression field as Some("bzip2"), so we do as well. We haven’t found any examples of this in the wild, not even in the cache.nixos.org dataset.

§file_hash: Option<[u8; 32]>

SHA-256 digest of the file at url

§file_size: Option<u64>

Size of the file at url in bytes

Implementations§

source§

impl<'a> NarInfo<'a>

source

pub fn parse(input: &'a str) -> Result<Self, Error>

source

pub fn fingerprint(&self) -> String

Computes the fingerprint string for certain fields in this NarInfo. This fingerprint is signed in [self.signatures].
