2020-07-27Rollup merge of #73858 - tspiteri:const-methods, r=oli-obkManish Goregaokar-10/+10
Make more primitive integer methods const Now that #72437 has been merged and `const_if_match` is stable, these methods can be stabilized const. The methods are grouped in commits according to feature names: * `const_nonzero_int_methods` - `NonZero*::new` * some `const_checked_int_methods` - `{i*,u*}::checked_add` - `{i*,u*}::checked_sub` - `{i*,u*}::checked_mul` - `{i*,u*}::checked_neg` - `{i*,u*}::checked_shl` - `{i*,u*}::checked_shr` - `i*::checked_abs` * `const_saturating_int_methods` - `{i*,u*}::saturating_add` - `{i*,u*}::saturating_sub` - `{i*,u*}::saturating_mul` - `i*::saturating_neg` - `i*::saturating_abs` * `const_int_sign` - `i*::signum` * `const_ascii_ctype_on_intrinsics` - `{char,u8}::is_ascii_alphabetic` - `{char,u8}::is_ascii_uppercase` - `{char,u8}::is_ascii_lowercase` - `{char,u8}::is_ascii_alphanumeric` - `{char,u8}::is_ascii_digit` - `{char,u8}::is_ascii_hexdigit` - `{char,u8}::is_ascii_punctuation` - `{char,u8}::is_ascii_graphic` - `{char,u8}::is_ascii_whitespace` - `{char,u8}::is_ascii_control`

2020-06-13Adjusted some doctests in libcore to use `should_panic`.Jake Degen-45/+17
Previously, some doctests were spawning new threads and joining them to indicate that a particular call should panic; this hurt readability, so the tests have been adjusted to simply call the method and use the `should_panic` marker.

2020-05-21Rollup merge of #72371 - Elrendio:char_documentation, r=steveklabnikRalf Jung-2/+4
FIX - Char documentation for unexperienced users This is my first PR on rust and even if I've read [CONTRIBUTING.md](https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#pull-requests) I'm ensure everything is perfect. Sorry if I didn't follow the exact procedure. **What it does:** - Add an example in the char documentation **Explanation** Unexperienced users might not know that punctuation is `Case_Ignorable` and not `Uppercase` and `Lowercase` which mean that when checking if a string is uppercase one might be tempted to write: ```rust my_string.chars().all(char::is_uppercase) ``` However this will return false for `"HELLO WORLD"` which is not intuitive. Since the function `is_case_ignorable` doesn't exists I believe the correct way to check is: ```rust !my_string.chars().any(char::is_lowercase) ``` The aim of this example is to prevent unexperienced users to make an error which punctuation chars.

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-15/+3
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.

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.

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⟩.
