Implementations§

Source§

impl FileUtils

Source

pub fn create_tmp_file( content: &[u8], name: &str, ext: &str, tmp_dir: Option<&Path>, ) -> Result<PathBuf, Error>

创建临时文件并写入内容。

§参数
  • content:文件内容
  • name:文件名前缀
  • ext:扩展名(不含点)
  • tmp_dir:临时文件夹目录(None 时使用系统临时目录下的 wxjava-temp
§返回

临时文件路径。

Source

pub fn image_to_base64_by_stream<R: Read>( reader: &mut R, ) -> Result<String, Error>

将输入流转为 Base64 字符串。

对应 Java FileUtils.imageToBase64ByStream:读取流全部内容后以标准 Base64 编码返回。Java 读取失败时打印堆栈并返回 null,Rust 以 Result::Err 表达同一错误路径。
