Struct zingen::Constructor

pub struct Constructor {
    pub masm: MacroAssembler,
    pub init_code: Buffer,
    pub runtime_bytecode: Buffer,
}

Contract constructor.

Bytecode

• CREATE instruction
• INIT_CODE
  • INIT_LOGIC
  • RETURN RUNTIME_BYTECODE
• RUNTIME_BYTECODE

TODO: introduce ABI for constructor

Fields

masm: MacroAssembler

Code generator.

init_code: Buffer

Code buffer.

runtime_bytecode: Buffer

Runtime bytecode.

Implementations

impl Constructor

pub fn new( constructor: Option<FuncType>, runtime_bytecode: Buffer ) -> Result<Self>

Create a new constructor.

pub fn finish(&mut self) -> Result<Buffer>

Concat the constructor code.

Here we override the memory totally with the runtime bytecode.

fn return_instr_length( init_code_length: usize, runtime_bytecode_length: usize ) -> usize

Returns the length of instructions.
