FirmwareVersionState

Struct FirmwareVersionState 

Source
pub struct FirmwareVersionState {
    pub hardware_timestamp_us: u64,
    pub system_timestamp_us: u64,
    pub firmware_data: Vec<u8>,
    pub is_complete: bool,
    pub version_string: Option<String>,
}
Expand description

固件版本状态

更新频率:按需查询 CAN ID:0x4AF(多帧累积) 同步机制:RwLock(冷数据,更新频率低)

Fields§

§hardware_timestamp_us: u64

硬件时间戳(微秒,最后一帧的时间)

§system_timestamp_us: u64

系统接收时间戳(微秒)

§firmware_data: Vec<u8>

累积的固件数据(字节数组) 注意:版本字符串需要从累积数据中解析

§is_complete: bool

是否已收到完整数据 注意:判断条件需要根据实际情况确定(例如收到特定结束标记)

§version_string: Option<String>

解析后的版本字符串(缓存) 如果 firmware_data 中包含有效的版本字符串,这里存储解析结果

Implementations§

Source§

impl FirmwareVersionState

Source

pub fn clear(&mut self)

清空累积的固件数据(用于开始新的查询)

在发送新的固件版本查询命令前调用此方法,清空之前累积的数据。

Source

pub fn check_completeness(&mut self) -> bool

检查数据是否完整(是否找到 S-V 标记且有足够数据)

数据完整的条件:

  1. 找到 “S-V” 标记
  2. 从 S-V 开始至少有 8 字节数据
§返回值

如果数据完整,返回 true 并更新 is_complete 字段

Source

pub fn parse_version(&mut self) -> Option<String>

尝试从累积数据中解析版本字符串

解析成功时会自动更新 version_stringis_complete 状态。

Source

pub fn version_string(&self) -> Option<&String>

获取版本字符串(如果已解析)
