2019-11-26Format libcore with rustfmtDavid Tolnay-37/+86
This commit applies rustfmt with default settings to files in src/libcore *that are not involved in any currently open PR* to minimize merge conflicts. The list of files involved in open PRs was determined by querying GitHub's GraphQL API with this script: https://gist.github.com/dtolnay/aa9c34993dc051a4f344d1b10e4487e8 With the list of files from the script in `outstanding_files`, the relevant commands were: $ find src/libcore -name '*.rs' | xargs rustfmt --edition=2018 $ rg libcore outstanding_files | xargs git checkout -- Repeating this process several months apart should get us coverage of most of the rest of libcore.

2017-05-09fix confusion about parts required for float formattingNathan Froyd-4/+4
The documentation for flt2dec doesn't match up with the actual implementation, so fix the documentation to align with reality. Presumably due to the mismatch, the formatting code for floats in std::fmt can use correspondingly shorter arrays in some places, so fix those places up as well. Fixes #41304.
2017-04-28fmt: use mem::uninitialized for float formatting buffersNathan Froyd-22/+34
Spending time to initialize these is just wasted work, as we'll overwrite them soon anyway. Fixes #41259.
2017-04-28fmt: use the minimum parts array sizeNathan Froyd-4/+4
The comments for flt2dec::to_shortest_str says that we only need a slice of length 5 for the parts array. Initializing a 16-part array is just wasted effort and wasted stack space. Other functions in the flt2dec module have similar comments, so we adjust the parts arrays passed to those functions accordingly.
2017-04-28fmt: reduce the stack space required by float formattingNathan Froyd-16/+66
For the two major entry points for float formatting, we split the exact case and the shortest cases into separate functions. We mark the separate functions as #[inline(never) so the exact cases won't bloat stack space in their callers unnecessarily. The shortest cases are marked so for similar reasons. Fixes #41234.

* Move to a separate float mod * Add more tests for f64 f32 lower exp upper exp * Use assert_eq for a clearer error message
2015-05-06core: made the core formatter to use a new flt2dec.Kang Seonghoon-289/+0
As a side effect `core::fmt::float` is gone now. This also slightly changes the float output, so this is: [breaking-change]
2015-04-21std: Remove deprecated/unstable num functionalityAlex Crichton-14/+29
This commit removes all the old casting/generic traits from `std::num` that are no longer in use by the standard library. This additionally removes the old `strconv` module which has not seen much use in quite a long time. All generic functionality has been supplanted with traits in the `num` crate and the `strconv` module is supplanted with the [rust-strconv crate][rust-strconv]. [rust-strconv]: https://github.com/lifthrasiir/rust-strconv This is a breaking change due to the removal of these deprecated crates, and the alternative crates are listed above. [breaking-change]

2015-03-30std: Standardize (input, output) param orderingsAlex Crichton-2/+2
This functions swaps the order of arguments to a few functions that previously took (output, input) parameters, but now take (input, output) parameters (in that order). The affected functions are: * ptr::copy * ptr::copy_nonoverlapping * slice::bytes::copy_memory * intrinsics::copy * intrinsics::copy_nonoverlapping Closes #22890 [breaking-change]
2015-03-28Remove IteratorExtSteven Fackler-1/+1
All methods are inlined into Iterator with `Self: Sized` bounds to make sure Iterator is still object safe. [breaking-change]

Now that support has been removed, all lingering use cases are renamed.

2015-03-03Rollup merge of #22876 - Florob:const, r=nikomatsakisManish Goregaokar-1/+1
This changes the type of some public constants/statics in libunicode. Notably some `&'static &'static [(char, char)]` have changed to `&'static [(char, char)]`. The regexp crate seems to be the sole user of these, yet this is technically a [breaking-change]
2015-03-02core: Audit num module for int/uintBrian Anderson-2/+2
* count_ones/zeros, trailing_ones/zeros return u32, not usize * rotate_left/right take u32, not usize * RADIX, MANTISSA_DIGITS, DIGITS, BITS, BYTES are u32, not usize Doesn't touch pow because there's another PR for it. [breaking-change]

2015-01-01std: Enforce Unicode in fmt::WriterAlex Crichton-10/+10
This commit is an implementation of [RFC 526][rfc] which is a change to alter the definition of the old `fmt::FormatWriter`. The new trait, renamed to `Writer`, now only exposes one method `write_str` in order to guarantee that all implementations of the formatting traits can only produce valid Unicode. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md One of the primary improvements of this patch is the performance of the `.to_string()` method by avoiding an almost-always redundant UTF-8 check. This is a breaking change due to the renaming of the trait as well as the loss of the `write` method, but migration paths should be relatively easy: * All usage of `write` should move to `write_str`. If truly binary data was being written in an implementation of `Show`, then it will need to use a different trait or an altogether different code path. * All usage of `write!` should continue to work as-is with no modifications. * All usage of `Show` where implementations just delegate to another should continue to work as-is. [breaking-change] Closes #20352
