Struct ContentHash 

pub struct ContentHash(/* private fields */);

Content-addressable hash encoded as 32 raw bytes and serialized as hex.

Implementations

impl ContentHash

pub fn new(bytes: [u8; 32]) -> ContentHash

Create a new content hash from raw bytes.

pub fn from_hex(hex: &str) -> ContentHash

Create a content hash from a hex string.

Panics

Panics if the hex string is not exactly 64 hexadecimal characters.

pub fn as_bytes(&self) -> &[u8; 32]

Borrow the raw bytes.

pub fn to_hex(&self) -> String

Convert to lowercase hex.

pub fn zero() -> ContentHash

The zero hash, useful for deterministic stubs.

Trait Implementations

impl Clone for ContentHash

fn clone(&self) -> ContentHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentHash

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

Formats the value using the given formatter.

impl Default for ContentHash

fn default() -> ContentHash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContentHash

fn deserialize<__D>( __deserializer: __D, ) -> Result<ContentHash, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContentHash

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

Formats the value using the given formatter.

impl Hash for ContentHash

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

where __H: Hasher,

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 PartialEq for ContentHash

fn eq(&self, other: &ContentHash) -> 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 Serialize for ContentHash

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
