Trait BackendExternalities

pub trait BackendExternalities: Externalities + CountersOwner {
    // Required methods
    fn gas_amount(&self) -> GasAmount;
    fn pre_process_memory_accesses(
        &mut self,
        reads: &[MemoryInterval],
        writes: &[MemoryInterval],
        gas_counter: &mut u64,
    ) -> Result<(), ProcessAccessError>;
}

Extended externalities that can manage gas counters.

Required Methods

fn gas_amount(&self) -> GasAmount

fn pre_process_memory_accesses( &mut self, reads: &[MemoryInterval], writes: &[MemoryInterval], gas_counter: &mut u64, ) -> Result<(), ProcessAccessError>

Pre-process memory access if needed.

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.
