Usage

Assembler

• assemble_one

rust use revmasm::{ assembler::assemble_one, types::bytecodes::bytecodes_to_hex, }; let instr = "PUSH32 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"; let bc = assemble_one(instr.to_string()).unwrap(); assert_eq!( bytecodes_to_hex(&bc), "7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" );

• assemble

```rust use revmasm::{ assembler::assemble, types::bytecodes::bytecodestohex, };

let instrs1 = "PUSH1 0x80 \nPUSH1 0x40\nMSTORE\nPUSH1 0x04\nCALLDATASIZE\nLT\nPUSH1 0x3f\nJUMPI\nPUSH1 0x00\nCALLDATALOAD"; let bc1 = assemble(instrs1.tostring()).unwrap(); asserteq!( bytecodestohex(&bc1), "608060405260043610603f57600035".to_string() );

let instrs2 = "PUSH2 0xf1f1\nPUSH2 0x0203"; let bc2 = assemble(instrs2.tostring()).unwrap(); asserteq!(bytecodestohex(&bc2), "61f1f1610203".to_string()); ```

Disassembler

• disassemble

```rust use revmasm::{ disassembler::disassemble, types::bytecodes::Bytecodes }; let input1 = "608060405260043610603f57600035"; let input2 = "61F1F1610203";

let bc1 = Bytecodes::from(input1.tostring()); let bc2 = Bytecodes::from(input2.tostring()); disassemble(bc1); disassemble(bc2); ```
