Type Alias frame_support::traits::tokens::fungibles::Debt

pub type Debt<AccountId, B> = Imbalance<<B as Inspect<AccountId>>::AssetId, <B as Inspect<AccountId>>::Balance, <B as Balanced<AccountId>>::OnDropDebt, <B as Balanced<AccountId>>::OnDropCredit>;

Imbalance implying that the total_issuance value is less than the sum of all account balances.

Aliased Type

struct Debt<AccountId, B> { /* private fields */ }

Implementations

impl<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> Imbalance<A, B, OnDrop, OppositeOnDrop>

pub fn zero(asset: A) -> Self

pub fn drop_zero(self) -> Result<(), Self>

pub fn split(self, amount: B) -> (Self, Self)

pub fn extract(&mut self, amount: B) -> Self

Mutate self by extracting a new instance with at most amount value, reducing self accordingly.

pub fn merge(self, other: Self) -> Result<Self, (Self, Self)>

pub fn subsume(&mut self, other: Self) -> Result<(), Self>

pub fn offset( self, other: Imbalance<A, B, OppositeOnDrop, OnDrop>, ) -> Result<SameOrOther<Self, Imbalance<A, B, OppositeOnDrop, OnDrop>>, (Self, Imbalance<A, B, OppositeOnDrop, OnDrop>)>

pub fn peek(&self) -> B

pub fn asset(&self) -> A

Trait Implementations

impl<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> Debug for Imbalance<A, B, OnDrop, OppositeOnDrop>

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

Formats the value using the given formatter.

impl<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> Drop for Imbalance<A, B, OnDrop, OppositeOnDrop>

fn drop(&mut self)

Executes the destructor for this type.

impl<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> PartialEq for Imbalance<A, B, OnDrop, OppositeOnDrop>

fn eq(&self, other: &Self) -> 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<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> TryDrop for Imbalance<A, B, OnDrop, OppositeOnDrop>

fn try_drop(self) -> Result<(), Self>

Drop an instance cleanly. Only works if its value represents “no-operation”.

impl<A: AssetId, B: Balance, OnDrop: HandleImbalanceDrop<A, B>, OppositeOnDrop: HandleImbalanceDrop<A, B>> TryMerge for Imbalance<A, B, OnDrop, OppositeOnDrop>

fn try_merge(self, other: Self) -> Result<Self, (Self, Self)>

Consume self and an other to return a new instance that combines both. Errors with Err(self, other) if the imbalances cannot be merged (e.g. imbalances of different assets).
