Trait Decimals

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

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

Implemented by all decimal types usable in ManagedDecimal.

Required Methods

fn num_decimals(&self) -> usize

Number of decimals as variable.

Provided Methods

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

where M: ManagedTypeApi,

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.
