2019-02-10libs: doc commentsAlexander Regueiro-2/+2
2019-02-08Use write_char for writing padding charactersNick Fitzgerald-22/+8
Removes some unsafe *and* saves almost half a kilobyte of code size.
2019-02-08Also de-duplicate 32- and 64-bit number formatting on wasm32Nick Fitzgerald-8/+18
2019-02-07Un-monomorphize and inline formatting with paddingNick Fitzgerald-29/+57
The generic `F` in `with_padding` was causing a bunch of stuff to get inlined that otherwise needn't be, blowing up code size.
2019-02-07De-duplicate write_prefix lambda in pad_integralNick Fitzgerald-11/+20
For smaller code size.
2019-02-07De-duplicate number formatting implementations for smaller code sizeNick Fitzgerald-31/+38
Instead of inlining the same logic into every number formatting implementation, pull it out into a function that each of the number formatting impls call into.

Small perf improvement for fmt Added benchmark is based on #10761
2019-01-19Rollup merge of #57452 - steveklabnik:improve-formatter-docs, r=frewsxcvMazdak Farrokhzad-3/+12
Improve docs for Formatter Some improvements to `std::fmt::Formatter` to make it a bit more consistent with other documentation, as well as calling out that you don't ever instantiate one yourself.

2018-04-20Revert stabilization of `feature(never_type)`.Felix S. Klock II-2/+2
This commit is just covering the feature gate itself and the tests that made direct use of `!` and thus need to opt back into the feature. A follow on commit brings back the other change that motivates the revert: Namely, going back to the old rules for falling back to `()`.
2018-04-13core: Remove an implicit panic from Formatter::padAlex Crichton-1/+5
The expression `&s[..i]` in general can panic if `i` is out of bounds or not on a character boundary for a string, and this caused the codegen for `Formatter::pad` to be a bit larger than it otherwise needed to be. This commit replaces this with `s.get(..i).unwrap_or(&s)` which while having different behavior if `i` is out of bounds has a much smaller code footprint and otherwise avoids the need for `unsafe` code.
2018-04-03tweak fmt::Arguments docsAlex Burka-6/+5
Remove an outdated claim about passing something or other to a function. Also swap the variable names in the example.
2018-03-26Rollup merge of #49103 - glandium:uninitialized, r=cramertjTim Neumann-1/+1
Use an uninitialized buffer in GenericRadix::fmt_int, like in Display::fmt for numeric types The code using a slice of that buffer is only ever going to use bytes that are subsequently initialized.
2018-03-25Rollup merge of #49229 - Centril:doc/format_args_display_debug, r=steveklabnikkennytm-6/+66
Document format_args! / Arguments<'a> behavior wrt. Display and Debug This is a follow up PR to #49067 , this documents the behavior of `format_args!` (i.e: `Argument<'a>`) wrt. `Display` and `Debug`. r? @steveklabnik
2018-03-23Rollup merge of #49102 - glandium:decimal, r=aturonAlex Crichton-5/+0
Remove core::fmt::num::Decimal Before ebf9e1aaf6, it was used for Display::fmt, but ebf9e1aaf6 replaced that with a faster implementation, and nothing else uses it.
