封闭类:

@FieldOrder({"bits","_padIo1","bytes","ptr","offset","startbit","_padIo2","_padIo3"}) public static class Structures.SlaveIoDesc extends com.sun.jna.Structure
Slave I/O 描述符 - 对应 C 端 slave_io_desc_t 原平面字段 Obits/Obytes/outputs/Ooffset/Ostartbit (×2 输入/输出) 收敛为 sub-struct. 嵌入到 EcSlave 中段 (Dtype 之后, SM 之前) 各 1 个 (output / input). 64 位下: bits (2) + 2 字节填充 + bytes (4) + ptr (8) + offset (4) + startbit (1) + 3 字节尾填充 = 24 字节. JNA 自然对齐自动处理填充, 我们显式声明 _padN 字段确保布局正确.
