Trait BackendExternalities

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

Extended externalities that can manage gas counters.

Required Methods

fn into_ext_info(self, memory: &impl Memory) -> Result<ExtInfo, MemoryError>

fn gas_amount(&self) -> GasAmount

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

Pre-process memory access if need.

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.
