Struct PartialStorage

pub struct PartialStorage { /* private fields */ }

A partial representation of an account storage, containing only a subset of the storage data.

Partial storage is used to provide verifiable access to specific segments of account storage without the need to provide the full storage data. It contains all needed parts for loading account storage data into the transaction kernel.

Implementations

impl PartialStorage

pub fn new( header: AccountStorageHeader, storage_map_proofs: Vec<SmtProof>, ) -> Self

Returns a new instance of partial storage with the specified header and storage map proofs.

The storage commitment is computed during instantiation based on the provided header.

pub fn storage_map_proofs(&self) -> &[SmtProof]

Returns a reference to the storage map proofs of this partial storage.

pub fn header(&self) -> &AccountStorageHeader

Returns a reference to the header of this partial storage.

pub fn commitment(&self) -> Digest

Returns the commitment of this partial storage.

pub fn get_item(&self, index: u8) -> Result<Digest, AccountError>

Returns the value of the storage slot at the specified slot index.

Errors:

• If the index is out of bounds

Trait Implementations

impl Clone for PartialStorage

fn clone(&self) -> PartialStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartialStorage

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

Formats the value using the given formatter.

impl Deserializable for PartialStorage

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl From<&AccountStorage> for PartialStorage

fn from(account_storage: &AccountStorage) -> Self

Converts a full account storage into a partial storage representation.

This creates a partial storage that contains proofs for all key-value pairs in all map slots of the account storage.

impl PartialEq for PartialStorage

fn eq(&self, other: &PartialStorage) -> 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 Serializable for PartialStorage

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
