Struct precompile_utils::precompile_set::PrecompileSetBuilder

pub struct PrecompileSetBuilder<R, P> { /* private fields */ }

Wraps a tuple of PrecompileSetFragment to make a real PrecompileSet.

Implementations

impl<R: Config, P: PrecompileSetFragment> PrecompileSetBuilder<R, P>

pub fn new() -> Self

Create a new instance of the PrecompileSet.

pub fn used_addresses() -> impl Iterator<Item = R::AccountId>

Return the list of mapped addresses contained in this PrecompileSet.

pub fn used_addresses_h160() -> impl Iterator<Item = H160>

Return the list of H160 addresses contained in this PrecompileSet.

pub fn summarize_checks(&self) -> Vec<PrecompileCheckSummary>

Trait Implementations

impl<R: Config, P: PrecompileSetFragment> Default for PrecompileSetBuilder<R, P>

fn default() -> Self

Returns the “default value” for a type.

impl<R, P: IsActivePrecompile> IsActivePrecompile for PrecompileSetBuilder<R, P>

fn is_active_precompile(&self, address: H160, gas: u64) -> IsPrecompileResult

Is the provided address an active precompile, a precompile that has not be deactivated. Note that a deactivated precompile is still considered a precompile for the EVM, but it will always revert when called.

impl<R: Config, P: PrecompileSetFragment> PrecompileSet for PrecompileSetBuilder<R, P>

fn execute( &self, handle: &mut impl PrecompileHandle ) -> Option<PrecompileResult>

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, gas: u64) -> IsPrecompileResult

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.
