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

Feature	Functions Included

with-toml	load_toml, save_toml
bin-nums	save_be_f64, load_be_f64, save_le_f64, ...
full	All the above.
default	None of the above. See below.

API Change 0.2.0 from 0.1.x

• API CHANGE - now .file_name() and .file_stem() returns Option<&str> use .name(), .stem() to have &str

Concept

simple-fs operates under the assumption that paths which are not utf8 are not visible to the API, which simplifies 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 the 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!
