Struct AccountVaultDelta 

pub struct AccountVaultDelta { /* private fields */ }

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

The difference is represented as follows:

• fungible: a binary tree map of fungible asset balance changes in the account vault.
• non_fungible: a binary tree map of non-fungible assets that were added to or removed from the account vault.

Implementations

impl AccountVaultDelta

pub const fn new( fungible: FungibleAssetDelta, non_fungible: NonFungibleAssetDelta, ) -> AccountVaultDelta

Validates and creates an AccountVaultDelta with the given fungible and non-fungible asset deltas.

Errors

Returns an error if the delta does not pass the validation.

pub fn fungible(&self) -> &FungibleAssetDelta

Returns a reference to the fungible asset delta.

pub fn non_fungible(&self) -> &NonFungibleAssetDelta

Returns a reference to the non-fungible asset delta.

pub fn is_empty(&self) -> bool

Returns true if this vault delta contains no updates.

pub fn add_asset(&mut self, asset: Asset) -> Result<(), AccountDeltaError>

Tracks asset addition.

pub fn remove_asset(&mut self, asset: Asset) -> Result<(), AccountDeltaError>

Tracks asset removal.

pub fn merge( &mut self, other: AccountVaultDelta, ) -> Result<(), AccountDeltaError>

Merges another delta into this one, overwriting any existing values.

The result is validated as part of the merge.

Errors

Returns an error if the resulted delta does not pass the validation.

impl AccountVaultDelta

pub fn from_iters( added_assets: impl IntoIterator<Item = Asset>, removed_assets: impl IntoIterator<Item = Asset>, ) -> AccountVaultDelta

Available on crate features testing only.

Creates an AccountVaultDelta from the given iterators.

pub fn added_assets(&self) -> impl Iterator<Item = Asset>

Available on crate features testing only.

Returns an iterator over the added assets in this delta.

pub fn removed_assets(&self) -> impl Iterator<Item = Asset>

Available on crate features testing only.

Returns an iterator over the removed assets in this delta.

Trait Implementations

impl Clone for AccountVaultDelta

fn clone(&self) -> AccountVaultDelta

Returns a duplicate 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<(), Error>

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>( source: &mut R, ) -> Result<AccountVaultDelta, DeserializationError>

where R: ByteReader,

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

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 AccountVaultDelta

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

where W: ByteWriter,

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

fn get_size_hint(&self) -> usize

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

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

Serializes self into a vector of bytes.
