Required Associated Types§
Required Methods§
Sourcefn set_spec(&mut self, spec: <CTX::Cfg as Cfg>::Spec) -> bool
fn set_spec(&mut self, spec: <CTX::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.
Sourcefn run(
&mut self,
context: &mut CTX,
inputs: &CallInputs,
) -> Result<Option<Self::Output>, String>
fn run( &mut self, context: &mut CTX, inputs: &CallInputs, ) -> Result<Option<Self::Output>, String>
Run the precompile.
Sourcefn warm_addresses(&self) -> Box<impl Iterator<Item = Address>>
fn warm_addresses(&self) -> Box<impl Iterator<Item = Address>>
Get the warm addresses.
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.
