File Metadata

Platform-independent file metadata and file type classification.

Fs::Metadata wraps the raw POSIX Stat record and exposes a portable API. Fs::FileType is an enum that classifies entries as regular files, directories, or symlinks without requiring callers to know about S_IFMT masks or DT_* constants.

Types

Construction

Users do not create Metadata directly. Instead, obtain it from:

• Fs::metadata(path) (stat by path)
• file.metadata() (fstat on open file)

Example

import Fs from "std::fs";
import Io from "std::io";

function main(): i32 {
  let result: Result<Fs::Metadata, Io::IoError> = Fs::metadata("/etc/hosts");
  if (result.isError()) {
    return 1;
  }

  let meta: Fs::Metadata = result.unwrap();
  if (meta.isFile()) {
    let size: i64 = meta.len();
    return 0;
  }

  return 1;
}
