Implementations§

source§

impl NixHash

source

pub fn algo(&self) -> HashAlgo

returns the algo as HashAlgo.

source

pub fn digest_as_bytes(&self) -> &[u8]

returns the digest as variable-length byte slice.

source

pub fn from_nix_hex_str(s: &str) -> Option<Self>

Constructs a NixHash from the Nix default hash format, the inverse of Self::to_nix_hex_string.

source

pub fn to_nix_hex_string(&self) -> String

Formats a NixHash in the Nix default hash format, which is the algo, followed by a colon, then the lower hex encoded digest.

source

pub(crate) fn to_nix_nixbase32_string(&self) -> String

Formats a NixHash in the format that’s used inside CAHash, which is the algo, followed by a colon, then the nixbase32-encoded digest.

source

pub fn to_plain_hex_string(&self) -> String

Returns the digest as a hex string – without any algorithm prefix.

impl Ord for NixHash

Same order as sorting the corresponding nixbase32 strings.

This order is used in the ATerm serialization of a derivation and thus affects the calculated output hash.

impl PartialEq for NixHash

source§

fn eq(&self, other: &NixHash) -> bool

This method tests for self and other values to be equal, and is used by ==.
