ResumeInfo

Struct ResumeInfo 

Source
pub struct ResumeInfo {
    pub url: Option<Url>,
    pub size: u64,
    pub progress: Vec<ProgressEntry>,
    pub elapsed: Duration,
}
Expand description

已保存、可续传下载的只读快照,由 DownloadState::snapshot 产出。

与引擎内部的 DownloadState(持有 Mutex 与脏标记、可持久化)不同,这是一个纯数据视图, 供 UI 等只读消费者在不持有内部 MutexGuard 的情况下读取进度元数据。

Fields§

§url: Option<Url>

持久化的初始 URL;旧 .fd 可能缺失,故为 Option

§size: u64

保存时记录的总大小;缺失时回退为 0

§progress: Vec<ProgressEntry>

已写入 .part 的字节区间(续传进度的唯一真相)。

§elapsed: Duration

跨所有续传累计的活跃下载时长。
