Struct HashedModuleData

pub struct HashedModuleData {
    hash: ModuleHash,
    wasm: OwnedBuffer,
}

A wrapper around Webassembly code and its hash.

Allows passing around WASM code and it’s hash without the danger of using a wrong hash.

Safe by construction: can only be created from a BinaryPackageCommand, which already has the hash embedded, or from bytes that will be hashed in the constructor.

Can be cloned cheaply.

Fields

hash: ModuleHash

wasm: OwnedBuffer

Implementations

impl HashedModuleData

pub fn new(bytes: impl Into<OwnedBuffer>) -> Self

pub fn new_sha256(bytes: impl Into<OwnedBuffer>) -> Self

pub fn new_xxhash(bytes: impl Into<OwnedBuffer>) -> Self

Create new HashedModuleData from the given bytes, hashing the the bytes into a [ModuleHash] with xxhash.

pub fn from_command(command: &BinaryPackageCommand) -> Self

Create new HashedModuleData from the given BinaryPackageCommand.

This is very cheap, as the hash is already available in the command.

pub fn hash(&self) -> &ModuleHash

Get the module hash.

pub fn wasm(&self) -> &OwnedBuffer

Get the WASM code.

pub fn into_parts(self) -> (ModuleHash, OwnedBuffer)

Trait Implementations

impl Clone for HashedModuleData

fn clone(&self) -> HashedModuleData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HashedModuleData

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

Formats the value using the given formatter.

impl PartialEq for HashedModuleData

fn eq(&self, other: &HashedModuleData) -> 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.
