Struct reth_revm::ContextPrecompiles

pub struct ContextPrecompiles<DB>
where
    DB: Database,
{ /* private fields */ }

Precompiles context.

Implementations

impl<DB> ContextPrecompiles<DB>

where DB: Database,

pub fn new(spec_id: PrecompileSpecId) -> ContextPrecompiles<DB>

Creates a new precompiles context at the given spec ID.

This is a cheap operation that does not allocate by reusing the global precompiles.

pub fn from_static_precompiles( precompiles: &'static Precompiles, ) -> ContextPrecompiles<DB>

Creates a new precompiles context from the given static precompiles.

NOTE: The internal precompiles must not be StatefulMut or call will panic. This is done because the default precompiles are not stateful.

pub fn from_precompiles( precompiles: HashMap<Address, ContextPrecompile<DB>>, ) -> ContextPrecompiles<DB>

Creates a new precompiles context from the given precompiles.

pub fn addresses_set(&self) -> HashSet<Address>

Returns precompiles addresses as a HashSet.

pub fn addresses<'a>( &'a self, ) -> Box<dyn ExactSizeIterator<Item = &'a Address> + 'a>

Returns precompiles addresses.

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

Returns true if the precompiles contains the given address.

pub fn call( &mut self, address: &Address, bytes: &Bytes, gas_limit: u64, evmctx: &mut InnerEvmContext<DB>, ) -> Option<Result<PrecompileOutput, PrecompileErrors>>

Call precompile and executes it. Returns the result of the precompile execution.

Returns None if the precompile does not exist.

pub fn to_mut(&mut self) -> &mut HashMap<Address, ContextPrecompile<DB>>

Returns a mutable reference to the precompiles map.

Clones the precompiles map if it is shared.

Trait Implementations

impl<DB> Clone for ContextPrecompiles<DB>

where DB: Database,

fn clone(&self) -> ContextPrecompiles<DB>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<DB> Default for ContextPrecompiles<DB>

where DB: Database,

fn default() -> ContextPrecompiles<DB>

Returns the “default value” for a type.

impl<DB> Extend<(Address, ContextPrecompile<DB>)> for ContextPrecompiles<DB>

where DB: Database,

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = (Address, ContextPrecompile<DB>)>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one #72631)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one #72631)

Reserves capacity in a collection for the given number of additional elements.

impl<DB> Extend<PrecompileWithAddress> for ContextPrecompiles<DB>

where DB: Database,

fn extend<T>(&mut self, iter: T)

where T: IntoIterator<Item = PrecompileWithAddress>,

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one #72631)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one #72631)

Reserves capacity in a collection for the given number of additional elements.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
