pub trait FeePay: StateWrite {
    // Provided method

        &'life0 mut self,
        gas_used: Gas,
        fee: Fee,
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: Send + 'async_trait,
             'life0: 'async_trait { ... }
}

Available on crate feature component only.

Allows payment of transaction fees.

Provided Methods

fn pay_fee<'life0, 'async_trait>( &'life0 mut self, gas_used: Gas, fee: Fee, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Uses the provided fee to pay for gas_used, erroring if the fee is insufficient.

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.
