Trait evm::executor::stack::PrecompileSet

pub trait PrecompileSet {
    fn execute(
        &self, 
        address: H160, 
        input: &[u8], 
        gas_limit: Option<u64>, 
        context: &Context, 
        is_static: bool
    ) -> Option<Result<PrecompileOutput, PrecompileFailure>>;
    fn is_precompile(&self, address: H160) -> bool;
}

A set of precompiles. Checks of the provided address being in the precompile set should be as cheap as possible since it may be called often.

Required methods

fn execute(
    &self,
    address: H160,
    input: &[u8],
    gas_limit: Option<u64>,
    context: &Context,
    is_static: bool
) -> Option<Result<PrecompileOutput, PrecompileFailure>>

Tries to execute a precompile in the precompile set. If the provided address is not a precompile, returns None.

fn is_precompile(&self, address: H160) -> bool

Check if the given address is a precompile. Should only be called to perform the check while not executing the precompile afterward, since execute already performs a check internally.

impl PrecompileSet for ()

fn execute(
    &self,
    _: H160,
    _: &[u8],
    _: Option<u64>,
    _: &Context,
    _: bool
) -> Option<Result<PrecompileOutput, PrecompileFailure>>

fn is_precompile(&self, _: H160) -> bool

impl PrecompileSet for BTreeMap<H160, PrecompileFn>

fn is_precompile(&self, address: H160) -> bool

Check if the given address is a precompile. Should only be called to perform the check while not executing the precompile afterward, since execute already performs a check internally.

fn execute(
    &self,
    address: H160,
    input: &[u8],
    gas_limit: Option<u64>,
    context: &Context,
    is_static: bool
) -> Option<Result<PrecompileOutput, PrecompileFailure>>
