Stabilize `std::convert` and related code

2015-03-31T18:24:38+00:00

* Marks `#[stable]` the contents of the `std::convert` module. * Added methods `PathBuf::as_path`, `OsString::as_os_str`, `String::as_str`, `Vec::{as_slice, as_mut_slice}`. * Deprecates `OsStr::from_str` in favor of a new, stable, and more general `OsStr::new`. * Adds unstable methods `OsString::from_bytes` and `OsStr::{to_bytes, to_cstring}` for ergonomic FFI usage.

convert: remove FromError, use From instead

2015-03-31T01:08:58+00:00

This removes the FromError trait, since it can now be expressed using the new convert::Into trait. All implementations of FromError where changed to From, and `try!` was changed to use From::from instead. Because this removes FromError, it is a breaking change, but fixing it simply requires changing the words `FromError` to `From`, and `from_error` to `from`. [breaking-change]

Revise use of conversion traits

2015-03-26T20:54:48+00:00

This commit revises `path` and `os_str` to use blanket impls for `From` on reference types. This both cuts down on the number of required impls, and means that you can pass through e.g. `T: AsRef` to `PathBuf::from` without an intermediate call to `as_ref`. It also makes a FIXME note for later generalizing the blanket impls for `AsRef` and `AsMut` to use `Deref`/`DerefMut`, once it is possible to do so.

Add generic conversion traits

2015-03-23T22:01:45+00:00

This commit: * Introduces `std::convert`, providing an implementation of RFC 529. * Deprecates the `AsPath`, `AsOsStr`, and `IntoBytes` traits, all in favor of the corresponding generic conversion traits. Consequently, various IO APIs now take `AsRef` rather than `AsPath`, and so on. Since the types provided by `std` implement both traits, this should cause relatively little breakage. * Deprecates many `from_foo` constructors in favor of `from`. * Changes `PathBuf::new` to take no argument (creating an empty buffer, as per convention). The previous behavior is now available as `PathBuf::from`. * De-stabilizes `IntoCow`. It's not clear whether we need this separate trait. Closes #22751 Closes #14433 [breaking-change]
