Module: BSV::Wallet::Serializer::CreateActionResult

Defined in:
lib/bsv/wallet/serializer/create_action_result.rb

Overview

BRC-103 serialiser for create_action result (call byte 1).

Wire layout (port of go-sdk/wallet/serializer/create_action_result.go):

[1 byte]           0x00 success sentinel (frame-level, already checked by Frame)
[flag + 32 bytes]  txid (wire-order) with flag byte: 0=absent, 1=present
[flag + int_bytes] tx (BEEF bytes) with flag byte: 0=absent, 1=present + varint_len
[optional_bytes]   no_send_change encoded outpoints (NegativeOne = nil)
[send_with_results] varint count + txid + status_byte each
[1 byte flag]      signable_transaction: 0=absent, 1=present
If signable_transaction present:
  [int_bytes]      tx (BEEF bytes)
  [int_bytes]      reference bytes
