Trait Decimals

pub trait Decimals {
    // Required method
    fn num_decimals(&self) -> NumDecimals;

    // Provided method
    fn scaling_factor<M: ManagedTypeApi>(
        &self,
    ) -> ManagedRef<'static, M, BigUint<M>> { ... }
}

Implemented by all decimal types usable in ManagedDecimal.

Required Methods

fn num_decimals(&self) -> NumDecimals

Number of decimals as variable.

Provided Methods

fn scaling_factor<M: ManagedTypeApi>( &self, ) -> ManagedRef<'static, M, BigUint<M>>

10^num_decimals, represented as a BigUint.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
