Struct Hash32 

pub struct Hash32(pub [u8; 32]);

A 32-byte hash value used for user identification.

This is a wrapper around [u8; 32] that provides convenient methods for creating, displaying, and parsing hash values.

Tuple Fields

0: [u8; 32]

Implementations

impl Hash32

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

Creates a new Hash32 from a 32-byte array.

pub const fn zero() -> Self

Creates a zero-filled Hash32.

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

Returns the inner byte array.

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

Returns the inner byte array as a mutable reference.

pub fn to_hex(&self) -> String

Converts the hash to a hexadecimal string.

pub fn from_hex(s: &str) -> Result<Self, PriceLevelError>

Creates a Hash32 from a hexadecimal string.

Errors

Returns an error if the string is not exactly 64 hex characters or contains invalid hex characters.

Trait Implementations

impl Clone for Hash32

fn clone(&self) -> Hash32

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hash32

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

Formats the value using the given formatter.

impl Default for Hash32

fn default() -> Hash32

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Hash32

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Hash32

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

Formats the value using the given formatter.

impl From<[u8; 32]> for Hash32

fn from(bytes: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<Hash32> for [u8; 32]

fn from(hash: Hash32) -> Self

Converts to this type from the input type.

impl FromStr for Hash32

type Err = PriceLevelError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Hash32

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 PartialEq for Hash32

fn eq(&self, other: &Hash32) -> 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 Hash32

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

where S: Serializer,

Serialize this value into the given Serde serializer.
