2020-04-23Stabilize UNICODE_VERSION (feature unicode_version)Pyfisch-3/+1
The feature will become stable in Rust 1.45. Noted that the value of UNICODE_VERSION is expected to change.
2020-04-11Store UNICODE_VERSION as a tuplePyfisch-2/+0
Remove the UnicodeVersion struct containing major, minor and update fields and replace it with a 3-tuple containing the version number. As the value of each field is limited to 255 use u8 to store them.
2020-02-11Improve `char::is_ascii_*` codeAndrea Canciani-10/+40
These methods explicitly check if a char is in a specific ASCII range, therefore the `is_ascii()` check is not needed, but LLVM seems to be unable to remove it. WARNING: this change improves the performance on ASCII `char`s, but complex checks such as `is_ascii_punctuation` become slower on non-ASCII `char`s.

2019-11-26Format libcore with rustfmtDavid Tolnay-83/+57
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.

2019-09-04remove XID and Pattern_White_Space unicode tables from libcoreAleksey Kladov-23/+0
They are only used by rustc_lexer, and are not needed elsewhere. So we move the relevant definitions into rustc_lexer (while the actual unicode data comes from the unicode-xid crate) and make the rest of the compiler use it.

2019-07-22add rustc_private as a proper language feature gateAleksey Kladov-7/+12
At the moment, `rustc_private` as a (library) feature exists by accident: `char::is_xid_start`, `char::is_xid_continue` methods in libcore define it.

2018-08-01Auto merge of #51609 - dscorbett:is_numeric, r=alexcrichtonbors-4/+4
Treat gc=No characters as numeric [`char::is_numeric`](https://doc.rust-lang.org/std/primitive.char.html#method.is_numeric) and [`char::is_alphanumeric`](https://doc.rust-lang.org/std/primitive.char.html#method.is_alphanumeric) are documented to be defined “in terms of the Unicode General Categories 'Nd', 'Nl', 'No'”, but unicode.py does not group 'No' with the other 'N' categories. These functions therefore currently return `false` for characters like ⟨¾⟩ and ⟨①⟩.
