Struct SerialDevice 

pub struct SerialDevice { /* private fields */ }

Implementations

impl SerialDevice

pub fn new(port_address: u16) -> Self

pub fn create_device(major: u16, minor: u16, port_address: u16) -> Device

创建一个串口字符设备实例，并封装为通用的 Device 结构。 用户需要手动指定 major/minor 号。

pub fn create_device_auto_assign(port_address: u16) -> Device

创建一个串口字符设备实例，并让 DeviceManager 自动分配 major/minor 号。
