用于编码具有预定义配置的多个结构的二进制编解码器

它仅适用于数组输入，因为它是为复杂结构创建的，可以检测最佳编码选项并返回针对大数组中的散列和整数的数据的最优化数据

编码流程

编码器使用pack进行编码和unpack进行解码，并进行了特殊修改和额外添加。

二进制包含数据

• 1字节协议版本
• 4字节元数据大小
• x字节元数据，包含pack信息和键，使用gzip编码
• x字节编码的二进制数据

使用示例

独特功能

编码器使用自动检测数据和最佳方式编码。

1. 十六进制字符串（例如交易散列）
2. 将大数字字符串转换为二进制，不丢失精度
3. 将大浮点数字符串转换为二进制，不丢失精度
4. 哈希表提取所有键并将其转换为纯文本
5. 整数大小由输入值确定，并使用较小的一个
