Enum Precompile

pub enum Precompile {
    Standard(fn(_: &Bytes, _: u64) -> Result<PrecompileOutput, PrecompileErrors>),
    Env(fn(_: &Bytes, _: u64, _: &Env) -> Result<PrecompileOutput, PrecompileErrors>),
    Stateful(Arc<dyn StatefulPrecompile>),
    StatefulMut(Box<dyn StatefulPrecompileMut>),
}

Precompile and its handlers.

Variants

Standard(fn(_: &Bytes, _: u64) -> Result<PrecompileOutput, PrecompileErrors>)

Standard simple precompile that takes input and gas limit.

Env(fn(_: &Bytes, _: u64, _: &Env) -> Result<PrecompileOutput, PrecompileErrors>)

Similar to Standard but takes reference to environment.

Stateful(Arc<dyn StatefulPrecompile>)

Stateful precompile that is Arc over StatefulPrecompile trait. It takes a reference to input, gas limit and environment.

StatefulMut(Box<dyn StatefulPrecompileMut>)

Mutable stateful precompile that is Box over StatefulPrecompileMut trait. It takes a reference to input, gas limit and environment.

Implementations

impl Precompile

pub fn new_stateful<P>(p: P) -> Precompile

where P: StatefulPrecompile + 'static,

Create a new stateful precompile.

pub fn new_stateful_mut<P>(p: P) -> Precompile

where P: StatefulPrecompileMut + 'static,

Create a new mutable stateful precompile.

pub fn call( &mut self, bytes: &Bytes, gas_limit: u64, env: &Env, ) -> Result<PrecompileOutput, PrecompileErrors>

Call the precompile with the given input and gas limit and return the result.

pub fn call_ref( &self, bytes: &Bytes, gas_limit: u64, env: &Env, ) -> Result<PrecompileOutput, PrecompileErrors>

Call the precompile with the given input and gas limit and return the result.

Returns an error if the precompile is mutable.

Trait Implementations

impl Clone for Precompile

fn clone(&self) -> Precompile

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Precompile

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
