Struct FungibleAssetDelta 

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

A binary tree map of fungible asset balance changes in the account vault.

Implementations

impl FungibleAssetDelta

pub fn new( map: BTreeMap<AccountId, i64>, ) -> Result<FungibleAssetDelta, AccountDeltaError>

Validates and creates a new fungible asset delta.

Errors

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

pub fn add(&mut self, asset: FungibleAsset) -> Result<(), AccountDeltaError>

Adds a new fungible asset to the delta.

Errors

Returns an error if the delta would overflow.

pub fn remove(&mut self, asset: FungibleAsset) -> Result<(), AccountDeltaError>

Removes a fungible asset from the delta.

Errors

Returns an error if the delta would overflow.

pub fn amount(&self, faucet_id: &AccountId) -> Option<i64>

Returns the amount of the fungible asset with the given faucet ID.

pub fn num_assets(&self) -> usize

Returns the number of fungible assets affected in the delta.

pub fn is_empty(&self) -> bool

Returns true if this vault delta contains no updates.

pub fn iter(&self) -> impl Iterator<Item = (&AccountId, &i64)>

Returns an iterator over the (key, value) pairs of the map.

pub fn merge( &mut self, other: FungibleAssetDelta, ) -> 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 result did not pass validation.

Trait Implementations

impl Clone for FungibleAssetDelta

fn clone(&self) -> FungibleAssetDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FungibleAssetDelta

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

Formats the value using the given formatter.

impl Default for FungibleAssetDelta

fn default() -> FungibleAssetDelta

Returns the “default value” for a type.

impl Deserializable for FungibleAssetDelta

fn read_from<R>( source: &mut R, ) -> Result<FungibleAssetDelta, 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 FungibleAssetDelta

fn eq(&self, other: &FungibleAssetDelta) -> 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 FungibleAssetDelta

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.
