The old issue has already been in FCP, a new issue was opened for the new API.
2018-08-03Provide `{to,from}_{ne,le,be}_bytes` functions on integersTobias Bucher-14/+86
If one doesn't view integers as containers of bytes, converting them to bytes necessarily needs the specfication of encoding. I think Rust is a language that wants to be explicit. The `to_bytes` function is basically the opposite of that – it converts an integer into the native byte representation, but there's no mention (in the function name) of it being very much platform dependent. Therefore, I think it would be better to replace that method by three methods, the explicit `to_ne_bytes` ("native endian") which does the same thing and `to_{le,be}_bytes` which return the little- resp. big-endian encoding.

Implement always-fallible TryFrom for usize/isize conversions that are infallible on some platforms This reverts commit 837d6c70233715a0ae8e15c703d40e3046a2f36a "Remove TryFrom impls that might become conditionally-infallible with a portability lint". This fixes #49415 by adding (restoring) missing `TryFrom` impls for integer conversions to or from `usize` or `isize`, by making them always fallible at the type system level (that is, with `Error=TryFromIntError`) even though they happen to be infallible on some platforms (for some values of `size_of::<usize>()`). They had been removed to allow the possibility to conditionally having some of them be infallible `From` impls instead, depending on the platforms, and have the [portability lint](https://github.com/rust-lang/rfcs/pull/1868) warn when they are used in code that is not already opting into non-portability. For example `#[allow(some_lint)] usize::from(x: u64)` would be valid on code that only targets 64-bit platforms. This PR gives up on this possiblity for two reasons: * Based on discussion with @aturon, it seems that the portability lint is not happening any time soon. It’s better to have the conversions be available *at all* than keep blocking them for so long. Portability-lint-gated platform-specific APIs can always be added separately later. * For code that is fine with fallibility, the alternative would force it to opt into "non-portability" even though there would be no real portability issue.

Closes #49137, the tracking issue for `NonZero*`, as this was the last remaining open question. Note that `ptr::NonNull<T>` already documents a similar guarantee.

const fn integer operations A follow up to #51171 Fixes #51267 Makes a lot of the integer methods (`swap_bytes`, `count_ones` etc) `const fn`s. See #51267 for a discussion about why this is wanted and the solution used.

Provide more context for what the {f32,f64}::EPSILON values represent. Introduce the 'machine epsilon' term because if one googles 'epsilon', they might stumble upon https://en.wikipedia.org/wiki/Epsilon_numbers_(mathematics) instead of https://en.wikipedia.org/wiki/Machine_epsilon

Add missing Wrapping methods, use doc_comment! Re-opened version of #49393 . Finishing touches for #32463. Note that this adds `Shl` and `Shr` implementations for `Wrapping<i128>` and `Wrapping<u128>`, which were previously missed. This is technically insta-stable, but I don't know why this would be a problem.
