Enum Precision

Source 
pub enum Precision {
    Exact,
    BestEffort,
}
Expand description

The precision required of an operation generally involving some aspect of quantitative fund withdrawal or transfer.

Variants§

§

Exact

The operation should must either proceed either exactly according to the amounts involved or not at all.

§

BestEffort

The operation may be considered successful even if less than the specified amounts are available to be used. In this case a best effort will be made.
