Struct fuel_merkle::sparse::MerkleTreeKey

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

The safe Merkle tree storage key prevents Merkle tree structure manipulations. The type contains only one constructor that hashes the storage key.

Implementations

impl MerkleTreeKey

pub fn new<B>(storage_key: B) -> Self

where B: AsRef<[u8]>,

The safe way to create a Self. It hashes the storage_key, making it entirely random and preventing SMT structure manipulation.

pub unsafe fn convert<B>(storage_key: B) -> Self

where B: Into<Bytes32>,

Unsafe analog to create a Self that doesn’t hash the storage_key unlike Self::new.

Safety

It is safe to use this method if you know that storage_key was randomly generated like ContractId or AssetId.

Trait Implementations

impl AsRef<[u8]> for MerkleTreeKey

fn as_ref(&self) -> &[u8]

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

impl AsRef<[u8; 32]> for MerkleTreeKey

fn as_ref(&self) -> &Bytes32

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

impl Clone for MerkleTreeKey

fn clone(&self) -> MerkleTreeKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleTreeKey

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

Formats the value using the given formatter.

impl Deref for MerkleTreeKey

type Target = [u8; 32]

The resulting type after dereferencing.

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

Dereferences the value.

impl From<MerkleTreeKey> for Bytes32

fn from(value: MerkleTreeKey) -> Self

Converts to this type from the input type.

impl Hash for MerkleTreeKey

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 MerkleTreeKey

fn eq(&self, other: &MerkleTreeKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
