Crate bytecode

Crate that contains bytecode types and opcode constants.

EOF bytecode contains its verification logic and only valid EOF bytecode can be created.

Legacy bytecode will always contain a jump table.

While EIP-7702 bytecode must contains a Address.

Modules

eof

legacy

opcode

EVM opcode definitions and utilities. It contains opcode information and utilities to work with opcodes.

utils

Structs

Eof

EVM Object Format (EOF) container

JumpTable

A table of valid jump destinations. Cheap to clone and memory efficient, one bit per opcode.

LegacyAnalyzedBytecode

Legacy analyzed bytecode represents the original bytecode format used in Ethereum.

LegacyRawBytecode

Used only as intermediate representation for legacy bytecode. Please check LegacyAnalyzedBytecode for the main structure that is used in Revm.

Enums

Bytecode

Main bytecode structure with all variants.

BytecodeDecodeError

EOF decode errors

CodeType

Types of code sections in EOF container

EofValidationError

EOF Validation Error

Constants

EOF_MAGIC

EOF Magic in u16 form

EOF_MAGIC_HASH

Hash of EF00 bytes that is used for EXTCODEHASH when called from legacy bytecode

Statics

EOF_MAGIC_BYTES

EOF magic number in array form

Functions

validate_eof

Fully validates an Eof container.

validate_eof_code

Validates that:

validate_eof_codes

Validates an Eof structure, without recursing into containers.

validate_eof_inner

validate_raw_eof

Decodes raw into an Eof container and validates it.

validate_raw_eof_inner

Decodes raw into an Eof container and validates it.
