Struct Sha256Hash 

pub struct Sha256Hash(/* private fields */);

A Sha256 hash.

Certain entities use this kind of hash as a key. It’s a small value which lives on the stack, as opposed to the longer, heap-allocated values which it replaces.

This type enables this use case with the new entity traits.

Implementations

impl Sha256Hash

pub fn hash_from(input: impl AsRef<[u8]>) -> Self

Create an instance by hashing a single input value.

pub fn from_existing_hash(hash: impl AsRef<[u8]>) -> CryptoKeystoreResult<Self>

Convert an existing hash into an instance of this type.

Only basic length checking is performed!

Trait Implementations

impl<__AsT: ?Sized> AsRef<__AsT> for Sha256Hash

where [u8; 32]: AsRef<__AsT>,

fn as_ref(&self) -> &__AsT

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Sha256Hash

fn clone(&self) -> Sha256Hash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sha256Hash

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

Formats the value using the given formatter.

impl Default for Sha256Hash

fn default() -> Sha256Hash

Returns the “default value” for a type.

impl Deref for Sha256Hash

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Sha256Hash

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

Formats the value using the given formatter.

impl From<[u8; 32]> for Sha256Hash

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

Converts to this type from the input type.

impl From<Sha256Hash> for [u8; 32]

fn from(value: Sha256Hash) -> Self

Converts to this type from the input type.

impl Hash for Sha256Hash

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 KeyType for Sha256Hash

fn bytes(&self) -> Cow<'_, [u8]>

Get a unique binary representation of this key.

impl Ord for Sha256Hash

fn cmp(&self, other: &Sha256Hash) -> 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 Sha256Hash

fn eq(&self, other: &Sha256Hash) -> 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 Sha256Hash

fn partial_cmp(&self, other: &Sha256Hash) -> 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 ToSql for Sha256Hash

Available on non-target_family=wasm only.

fn to_sql(&self) -> Result<ToSqlOutput<'_>>

Converts Rust value to SQLite value
