Enum Precompile

pub enum Precompile {
    Standard(StandardPrecompileFn),
    Env(EnvPrecompileFn),
    Stateful(StatefulPrecompileArc),
    StatefulMut(StatefulPrecompileBox),
}

Precompile and its handlers.

Variants

Standard(StandardPrecompileFn)

Standard simple precompile that takes input and gas limit.

Env(EnvPrecompileFn)

Similar to Standard but takes reference to environment.

Stateful(StatefulPrecompileArc)

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

StatefulMut(StatefulPrecompileBox)

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: StatefulPrecompile + 'static>(p: P) -> Self

Create a new stateful precompile.

pub fn new_stateful_mut<P: StatefulPrecompileMut + 'static>(p: P) -> Self

Create a new mutable stateful precompile.

pub fn call( &mut self, bytes: &Bytes, gas_limit: u64, env: &Env, ) -> PrecompileResult

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, ) -> PrecompileResult

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

Formats the value using the given formatter.

impl From<Arc<dyn StatefulPrecompile>> for Precompile

fn from(p: StatefulPrecompileArc) -> Self

Converts to this type from the input type.

impl From<Box<dyn StatefulPrecompileMut>> for Precompile

fn from(p: StatefulPrecompileBox) -> Self
