Required Methods

fn set_spec(&mut self, spec: <<CTX as ContextTr>::Cfg as Cfg>::Spec) -> bool

Sets the spec id and returns true if the spec id was changed. Initial call to set_spec will always return true.

Returned booling will determine if precompile addresses should be injected into the journal.

fn run( &mut self, context: &mut CTX, address: &Address, inputs: &InputsImpl, is_static: bool, gas_limit: u64, ) -> Result<Option<Self::Output>, String>

Run the precompile.

fn warm_addresses(&self) -> Box<impl Iterator<Item = Address>>

Get the warm addresses.

fn contains(&self, address: &Address) -> bool

Check if the address is a precompile.

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.
