Provider for precompiled contracts in the EVM.

Required Associated Types

type Output

The output type returned by precompile execution.

Required Methods

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.

Returns true if precompile addresses should be injected into the journal.

fn run( &mut self, context: &mut CTX, inputs: &CallInputs, ) -> Result<Option<Self::Output>, String>

Run the precompile.

fn warm_addresses(&self) -> &AddressSet

Get the warm addresses.

Provided Methods

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

Check if the address is a precompile.
