Crate bytecode

Expand description

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§

bitvec
bytecode: Module that contains the bytecode enum with all variants supported by Ethereum mainnet.
eip7702: EIP-7702 bytecode.
eof: EOF bytecode.
legacy: Legacy bytecode.
opcode: EVM opcode definitions and utilities. It contains opcode information and utilities to work with opcodes.
utils: Various utilities for the bytecode

BytecodeIterator: Iterator over opcodes in a bytecode, skipping immediates.
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.
OpCode: An EVM opcode

EOF_MAGIC: EOF Magic in u16 form
EOF_MAGIC_HASH: Hash of EF00 bytes that is used for EXTCODEHASH when called from legacy bytecode

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: Fully validates an Eof container. If first_code_type is None it will be auto deduced in verification process.
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.
