Module: BSV::Wallet::Serializer::DiscoverByAttributes

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

Overview

BRC-103 wire codec for the discover_by_attributes call (call byte 22).

Args wire layout:

[varint: attribute_count] per entry: [varint-int key_bytes][varint-int value_bytes]
[optional_uint32: limit]
[optional_uint32: offset]
[optional_bool: seek_permission]

Result wire layout: see DiscoverCertificatesResult.

Keys are written in sorted order (matching Go sort.Strings) to ensure deterministic encoding across SDK implementations.
