Values for `_SC_*` are not the same value between `macos` and `linux` so I've added specific target constants for Mac OS X and added `_SC_NPROCESSORS_ONLN` for `linux` and `macos`.
Closes#24374
It looks like `from_vec` was subsumed by new at some point,
but the documentation still refers to it as `from_vec`.
This updates the documentation for `from_vec_unchecked`
so that it properly says that it's the unchecked version of `new`.
Also, from_vec_unchecked requires a actual Vec<u8> while
new can take anything that is Into<Vec<u8>>, so I also
mention that in the documentation.
Since this is documentation:
r? @steveklabnik
- Adds two more functions for broadcast address and special
address classes reserved for documentation
- Modifies the globally routable IP check to include these
new functions
Fixes#24314
It was mistakenly calling `with_extension` with "foo.txt" instead of "txt".
I've also added an assert. This also calls more attention to the fact you get back a PathBuf, instead of a Path, which I feel is easy to miss when skimming.
The meaning of each variant of this enum was somewhat ambiguous and it's uncler
that we wouldn't even want to add more enumeration values in the future. As a
result this error has been altered to instead become an opaque structure.
Learning about the "first invalid byte index" is still an unstable feature, but
the type itself is now stable.
Since it doesn't utilize the parameter, it's not very idiomatic since it
could just use the `Result::or` method. So this changes the example to
utilize the parameter. As far as I can tell, all the numbers in this
example are completely arbitrary.
This is a little bit tricky, since with include_str!, we know that we
are including utf-8 content, so it's safe to store the source as a
String in a FileMap. We don't know that for include_bytes!, but I don't
think we actually need to track the contents anyways, so I'm passing "".
new_filemap does check for the zero length content, and it should be
reasonable, howeven I'm not sure if it would be better to pass None
instead of Some(Rc::new("")) as the src component of a FileMap.
Fixes bug #24348
`wrapping_div`, `wrapping_rem`, `wrapping_neg`,
`wrapping_shl`, `wrapping_shr`.
All marked unstable under `core` feature for now (with expectation of
being marked as stable by 1.0 release).
