Enum DataSource

Source
pub enum DataSource {
    StdReadFile,
    Folders(Vec<String>),
    TarInMemory(Vec<u8>),
    TarFile(TarFile),
    FileMap(HashMap<String, SingleFileSource>),
    Sync(Box<dyn SyncFolderSource + Send + Sync>),
    Async(Box<dyn AsyncFolderSource + Send + Sync>),
}
Expand description

Defines where to get the content of the requested file name.

很多配置中 都要再加载其他外部文件, FileSource 限定了 查找文件的 路径 和 来源, 读取文件时只会限制在这个范围内, 这样就增加了安全性

Variants§

§

StdReadFile

§

Folders(Vec<String>)

从指定的一组路径来寻找文件

§

TarInMemory(Vec<u8>)

从一个 已放到内存中的 tar 中 寻找文件

§

TarFile(TarFile)

§

FileMap(HashMap<String, SingleFileSource>)

与其它方式不同,FileMap 存储名称的映射表, 无需遍历目录

§

Sync(Box<dyn SyncFolderSource + Send + Sync>)

§

Async(Box<dyn AsyncFolderSource + Send + Sync>)
