Trait BalanceHolder 

pub trait BalanceHolder {
    // Required methods
    fn balance(&self) -> Result<Amount, ArithmeticError>;

    fn try_sub_assign(&mut self, other: Amount) -> Result<(), ArithmeticError>;
}

How to access the balance of an account.

Required Methods

fn balance(&self) -> Result<Amount, ArithmeticError>

Returns the balance of the account.

fn try_add_assign(&mut self, other: Amount) -> Result<(), ArithmeticError>

Adds the given amount to the balance.

fn try_sub_assign(&mut self, other: Amount) -> Result<(), ArithmeticError>

Subtracts the given amount from the balance.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
