Implementations

impl ModuleHash

pub fn xxhash_from_bytes(key: [u8; 8]) -> Self

Create a new ModuleHash from the raw xxhash hash.

pub fn sha256_from_bytes(key: [u8; 32]) -> Self

Create a new ModuleHash from the raw sha256 hash.

pub fn xxhash_parse_hex(hex_str: &str) -> Result<Self, FromHexError>

Parse a XXHash hash from a hex-encoded string.

pub fn sha256_parse_hex(hex_str: &str) -> Result<Self, FromHexError>

Parse a Sha256 hash from a hex-encoded string.

pub fn xxhash(wasm: impl AsRef<[u8]>) -> Self

Generate a new [ModuleCache] based on the XXHash hash of some bytes.

pub fn sha256(wasm: impl AsRef<[u8]>) -> Self

Generate a new [ModuleCache] based on the Sha256 hash of some bytes.

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

Get the raw hash.

Trait Implementations

impl Archive for ModuleHash

where [u8; 8]: Archive, [u8; 32]: Archive,

type Archived = ArchivedModuleHash

The archived representation of this type.

type Resolver = ModuleHashResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for ModuleHash

fn clone(&self) -> ModuleHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ModuleHash

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<ModuleHash, __D> for Archived<ModuleHash>

where [u8; 8]: Archive, <[u8; 8] as Archive>::Archived: Deserialize<[u8; 8], __D>, [u8; 32]: Archive, <[u8; 32] as Archive>::Archived: Deserialize<[u8; 32], __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ModuleHash, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for ModuleHash

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

Formats the value using the given formatter.

impl Hash for ModuleHash

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 ModuleHash

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

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

fn partial_cmp(&self, other: &ModuleHash) -> 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<__S: Fallible + ?Sized> Serialize<__S> for ModuleHash

where [u8; 8]: Serialize<__S>, [u8; 32]: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
