Struct pallet_balances::PositiveImbalance[−][src]

pub struct PositiveImbalance<T: Config<I>, I: 'static = ()>(_);
Expand description

Opaque, move-only struct with private fields that serves as a token denoting that funds have been created without any equal and opposite accounting.

Implementations

Create a new positive imbalance from a balance.

Returns the “default value” for a type. Read more

Basic drop handler will just square up the total issuance.

The oppositely imbalanced type. They come in pairs.

The zero imbalance. Can be destroyed with drop_zero.

Drop an instance cleanly. Only works if its self.value() is zero.

Consume self and return two independent instances; the first is guaranteed to be at most amount and the second will be the remainder. Read more

Consume self and an other to return a new instance that combines both. Read more

Consume an other to mutate self into a new instance that combines both. Read more

Consume self and along with an opposite counterpart to return a combined result. Read more

The raw value of self.

Consume self and return two independent instances; the amounts returned will be in approximately the same ratio as first:second. Read more

Consume self and add its two components, defined by the first component’s balance, element-wise to two pre-existing Imbalances. Read more

Consume self and add its two components, defined by the ratio first:second, element-wise to two pre-existing Imbalances. Read more

Consume self and add its two components, defined by the first component’s balance, element-wise into two pre-existing Imbalance refs. Read more

Consume self and add its two components, defined by the ratio first:second, element-wise to two pre-existing Imbalances. Read more

Consume self to mutate other so that it combines both. Just like subsume, only with reversed arguments. Read more

Consume self and maybe an other to return a new instance that combines both. Read more

Maybe consume an other to mutate self into a new instance that combines both. Read more

This method tests for self and other values to be equal, and is used by ==. Read more

This method tests for !=.

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

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
