Struct CommonUploadData 

Source
pub struct CommonUploadData {
    pub file_name: Option<String>,
    pub content: Vec<u8>,
    pub length: u64,
}
Expand description

通用文件上传数据。

承载上传文件的文件名、内容与长度;内容以字节切片形式持有 (对应 Java InputStream,Rust 侧由调用方提供 Vec<u8>)。

Fields§

§file_name: Option<String>

文件名,如 1.jpg

§content: Vec<u8>

文件内容

§length: u64

文件内容长度(字节数)

Implementations§

Source§

impl CommonUploadData

Source

pub fn new(file_name: Option<String>, content: Vec<u8>) -> Self

Source

pub fn from_file(file: &Path) -> Result<Self, Error>

从文件路径构建上传数据(读取整个文件到内存)。

§参数
  • file:文件路径
§返回

上传数据;读取失败时返回错误。
