Enum Hash

pub enum Hash {
    None,
    Sha512(Sha512),
}

The external hash of patches.

Variants

None

None is the hash of the “null patch”, which introduced a single root vertex at the beginning of the repository.

Sha512(Sha512)

Patch hashed using the SHA2-512 algorithm.

Implementations

impl Hash

pub fn from_binary(v: &[u8]) -> Option<Self>

Get a Hash from a binary slice. This function does not compute the digest of anything, it just converts types.

pub fn from_base58(base58: &str) -> Option<Self>

Decode a hash from a base58-encoded str.

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

This hash as a slice (nonempty iff SHA512). This method might disappear when new hashes are introduced.

pub fn as_ref(&self) -> HashRef<'_>

A borrowed version of this Hash, used for instance to query the databases.

pub fn of_slice(buf: &[u8]) -> Result<Hash, Error>

Create a Hash from the binary slice of the patch contents.

impl Hash

pub fn to_base58(&self) -> String

Encode this Hash in base64.

Trait Implementations

impl Clone for Hash

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hash

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Hash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Hash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Hash

fn cmp(&self, other: &Hash) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Hash

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Hash

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Hash

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Hash
