Struct miden_objects::accounts::delta::AccountVaultDelta

pub struct AccountVaultDelta {
    pub added_assets: Vec<Asset>,
    pub removed_assets: Vec<Asset>,
}

AccountVaultDelta stores the difference between the initial and final account vault states.

The difference is represented as follows:

• added_assets: a vector of assets that were added to the account vault.
• removed_assets: a vector of assets that were removed from the account vault.

Fields

added_assets: Vec<Asset>

removed_assets: Vec<Asset>

Implementations

impl AccountVaultDelta

pub fn empty() -> Self

Creates an empty AccountVaultDelta.

pub fn from_iterators<A, B>(added_assets: A, removed_assets: B) -> Self

where A: IntoIterator<Item = Asset>, B: IntoIterator<Item = Asset>,

Creates an AccountVaultDelta from the given iterators.

pub fn validate(&self) -> Result<(), AccountDeltaError>

Checks whether this vault delta is valid.

Errors

Returns an error if:

• The number added assets is greater than u16::MAX.
• The number of removed assets is greater than u16::MAX.
• The same asset was added more than once, removed more than once, or both added and removed.

pub fn is_empty(&self) -> bool

Returns true if this vault delta contains no updates.

Trait Implementations

impl Clone for AccountVaultDelta

fn clone(&self) -> AccountVaultDelta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccountVaultDelta

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

Formats the value using the given formatter.

impl Default for AccountVaultDelta

fn default() -> AccountVaultDelta

Returns the “default value” for a type.

impl Deserializable for AccountVaultDelta

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 PartialEq for AccountVaultDelta

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

impl Serializable for AccountVaultDelta

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.
