simple-fs

simple-fs is a crate that provides a set of convenient and common file APIs built on std::fs, walkdir, and globset.

Cargo Features

API Changes

• 0.4.0
  • Update to notify 8 (should not have any API Changes)
  • API CHANGE - SPath - Now SPath::from(&str/&String,String) (no need for try_from)
• 0.3.1 from 0.3.0
  • This is a fix; however, it can change behavior on list/iter files.
    • Previously, the glob * was traversing into subfolders /, which was not the intended behavior.
    • Now, in 0.3.1, it uses the glob literal_separator = true, so it won't descend further.
    • You can now use *.rs to list direct descendants and **/*.rs for nested files.
    • The glob also needs to include the dir given in the list; otherwise, set ListOptions.relative_glob = true to make it relative.
• 0.3.x from 0.2.x
  • API CHANGE - watch - changes the rx to be flume based (works on both sync/async).
• 0.2.0 from 0.1.x
  • API CHANGE - now .file_name() and .file_stem() return Option<&str>; use .name() or .stem() to get &str.

Concept

simple-fs operates under the assumption that paths which are not utf8 are not visible to the API, simplifying many of the path-related APIs.

The two constructs that follow this assumption are (both are just wrappers of PathBuf with some guarantees):

• SPath, which ensures that the contained path is a valid UTF-8 path and includes a file name.
• SFile, which carries the same guarantees as SPath but also checks if the file is_file(), confirming the file's existence at the time of SFile construction.

By establishing these rules, APIs such as .file_name(), .file_stem(), and .to_str() are much simpler, as they all return &str.

The crate also includes other convenient, common APIs:

• read_to_string, which reports the file path if not found.
• get_buf_reader, which also reports the file path if not found or in case of an error.
• iter_files(dir, include_globs: &[&str], exclude_globs: &[&str]) -> Result<impl Iter SFile>
• list_files(..same as iter_files..) -> Result<Vec<SFile>>
• ensure_dir(dir_path), ensure_file_dir(file_path)
• With features, see above.

For more control, it is recommended to use std::fs, walkdir, globset, and other crates directly.

This is a very early implementation, with more to come.

Happy coding!
