Struct HashedModuleData

Source
pub struct HashedModuleData {
    hash: ModuleHash,
    wasm: OwnedBuffer,
}
Expand description

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 [BinaryCommand], which already has the hash embedded, or from bytes that will be hashed in the constructor.

Can be cloned cheaply.

Implementations§

Source§

impl HashedModuleData

Source

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

Source

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

Source

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.

Source

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.

Source

pub fn hash(&self) -> &ModuleHash

Get the module hash.

Source

pub fn wasm(&self) -> &OwnedBuffer

Get the WASM code.

Source

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