From 8f0319ab9992700d11b3e1979acdc940c94ba17c Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Tue, 3 Mar 2015 19:18:29 -0800 Subject: [PATCH] std: Stabilize the `fs` module This commit performs a stabilization pass over the `std::fs` module now that it's had some time to bake. The change was largely just adding `#[stable]` tags, but there are a few APIs that remain `#[unstable]`. The following apis are now marked `#[stable]`: * `std::fs` (the name) * `File` * `Metadata` * `ReadDir` * `DirEntry` * `OpenOptions` * `Permissions` * `File::{open, create}` * `File::{sync_all, sync_data}` * `File::set_len` * `File::metadata` * Trait implementations for `File` and `&File` * `OpenOptions::new` * `OpenOptions::{read, write, append, truncate, create}` * `OpenOptions::open` - this function was modified, however, to not attempt to reject cross-platform openings of directories. This means that some platforms will succeed in opening a directory and others will fail. * `Metadata::{is_dir, is_file, len, permissions}` * `Permissions::{readonly, set_readonly}` * `Iterator for ReadDir` * `DirEntry::path` * `remove_file` - like with `OpenOptions::open`, the extra windows code to remove a readonly file has been removed. This means that removing a readonly file will succeed on some platforms but fail on others. * `metadata` * `rename` * `copy` * `hard_link` * `soft_link` * `read_link` * `create_dir` * `create_dir_all` * `remove_dir` * `remove_dir_all` * `read_dir` The following apis remain `#[unstable]`. * `WalkDir` and `walk` - there are many methods by which a directory walk can be constructed, and it's unclear whether the current semantics are the right ones. For example symlinks are not handled super well currently. This is now behind a new `fs_walk` feature. * `File::path` - this is an extra abstraction which the standard library provides on top of what the system offers and it's unclear whether we should be doing so. This is now behind a new `file_path` feature. * `Metadata::{accessed, modified}` - we do not currently have a good abstraction for a moment in time which is what these APIs should likely be returning, so these remain `#[unstable]` for now. These are now behind a new `fs_time` feature * `set_file_times` - like with `Metadata::accessed`, we do not currently have the appropriate abstraction for the arguments here so this API remains unstable behind the `fs_time` feature gate. * `PathExt` - the precise set of methods on this trait may change over time and some methods may be removed. This API remains unstable behind the `path_ext` feature gate. * `set_permissions` - we may wish to expose a more granular ability to set the permissions on a file instead of just a blanket "set all permissions" method. This function remains behind the `fs` feature. The following apis are now `#[deprecated]` * The `TempDir` type is now entirely deprecated and is [located on crates.io][tempdir] as the `tempdir` crate with [its source][github] at rust-lang/tempdir. [tempdir]: https://crates.io/crates/tempdir [github]: https://github.com/rust-lang/tempdir The stability of some of these APIs has been questioned over the past few weeks in using these APIs, and it is intentional that the majority of APIs here are marked `#[stable]`. The `std::fs` module has a lot of room to grow and the material is [being tracked in a RFC issue][rfc-issue].
