Implementations

impl NixHash

pub fn algo(&self) -> HashAlgo

returns the algo as HashAlgo.

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

returns the digest as variable-length byte slice.

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.

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.

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.

pub fn to_plain_hex_string(&self) -> String

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

Trait Implementations

impl Clone for NixHash

fn clone(&self) -> NixHash

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NixHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NixHash

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NixHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

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.

fn cmp(&self, other: &NixHash) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NixHash

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NixHash

fn partial_cmp(&self, other: &NixHash) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for NixHash

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<(HashAlgo, &[u8])> for NixHash

fn try_from(value: (HashAlgo, &[u8])) -> NixHashResult<Self>

Constructs a new NixHash by specifying HashAlgo and digest. It can fail if the passed digest length doesn’t match what’s expected for the passed algo.

type Error = Error

The type returned in the event of a conversion error.

impl Eq for NixHash

impl StructuralPartialEq for NixHash
