Module precompiles

Exposes types that can be used to extend pallet_revive with additional functionality.

In order to add a pre-compile:

• Implement Precompile on a type. Most likely another pallet.
• Add the type to a tuple passed into Config::Precompiles.
• Use the types inside the run module to test and benchmark your pre-compile.

Use alloy through our re-export in this module to implement Eth ABI.

Re-exports

pub use crate::AddressMapper;

pub use alloy_core as alloy;

Modules

run

Types to run a pre-compile during testing or benchmarking.

Structs

Diff

This type is used to describe a storage change when charging from the meter.

ExecError

Error returned by contract execution.

GasMeter

H160

Fixed-size uninterpreted hash type with 20 bytes (160 bits) size.

H256

Fixed-size uninterpreted hash type with 32 bytes (256 bits) size.

U256

Little-endian large integer type 256-bit unsigned integer.

Enums

AddressMatcher

Used by Precompile in order to declare at which addresses it will be called.

A pre-compile can error in the same way that a real contract can.

RuntimeCosts

Traits

Ext

Environment functions which are available to all pre-compiles.

ExtWithInfo

Environment functions which are available to pre-compiles with HAS_CONTRACT_INFO = true.

Precompile

Type that can be implemented in other crates to extend the list of pre-compiles.

Token

This trait represents a token that can be used for charging GasMeter. There is no other way of charging it.
