We can shave a further 2 `icmp`s by inlining `is_char_boundary` and rearranging the checks.
Add notes to the primitive integer and `NonZero` types clarifying the equivalence between `highest_one` and the `ilog2`/`checked_ilog2` methods for non-negative values.
- 调整 MaybeUninit::zeroed 文档中的 padding 字节说明 - 对齐 mem::zeroed 中不保证 padding 为零的表述
…ning Make the linker quiet by default and add linker command line arguments for explicit verbosity control: - no flag: no tracing output is emitted during successful links - `-v`: emit informational linker diagnostics - `-vv`: emit tracing-level linker diagnostics Also adjust the tracing formatter to produce linker-style output by disabling ANSI color sequences and omitting timestamps, tracing levels, and tracing targets.
* The documentation for `align_of_val()` and `Alignment::of_val()` did not explain its use in interacting with `dyn` types, and even contained the false statement that “Every reference to a value of the type `T` must be a multiple of this number”. This change removes that statement from everything except `align_of()`, and adds a mention of, and example code for, getting the alignment of a `dyn` value. * The documentation for `align_of_val_raw()` did not explain how it relates to other functions in the family. Now it does. * Added a caveat that the alignment of `i32` is not always 4, despite the examples asserting this.
Import resolution now happens in 2 phases: 1. We resolve all undetermined and collect their resolutions 2. Write all resolutions to the Resolver state. Repeat this untill we reach a fix point. + Bless tests
… imports the correct traits for `aarch64`. + run the generator to apply change.
- take ownership of the `Vec<&Impl>` instead of copying into another alloc - reuse `ImplString` to do natural sort ordering - lazy formatting
