The most important rule of lexicographical comparison is that two arrays of equal length will be compared until the first difference occured. The examples provided only focuses on the second rule that says that the shorter array will be filled with some T2 that is less than every T. Which is only possible because of the first rule.
I no longer say "polymorphic" since it's a bit ambiguous here.
In PR rust-lang#76130, I add a fourth field, which makes using a tuple variant somewhat unwieldy.
This reverts commit 7e2548f. Now I know why it was redefined: it seems like it's potentially because of the orphan rule. Here are the error messages: error[E0119]: conflicting implementations of trait `std::fmt::Debug` for type `!`: --> src/primitive_docs.rs:236:1 | 6 | impl Debug for ! { | ^^^^^^^^^^^^^^^^ | = note: conflicting implementation in crate `core`: - impl std::fmt::Debug for !; error[E0117]: only traits defined in the current crate can be implemented for arbitrary types --> src/primitive_docs.rs:236:1 | 6 | impl Debug for ! { | ^^^^^^^^^^^^^^^- | | | | | `!` is not defined in the current crate | impl doesn't use only types from inside the current crate | = note: define and implement a trait or new type instead

Similar to `-Z dump-mir-graphviz`, this adds the option to write HTML+CSS files that allow users to analyze the spans associated with MIR elements (by individual statement, just terminator, or overall basic block). This PR was split out from PR rust-lang#76004, and exposes an API for spanview HTML+CSS files that is also used to analyze code regions chosen for coverage instrumentation (in a follow-on PR). Rust compiler MCP rust-lang/compiler-team#278 Relevant issue: rust-lang#34701 - Implement support for LLVMs code coverage instrumentation
Previously, this would say no such macro existed, but this was misleading, since the macro _did_ exist, it was just already seen. - Say where the macro was previously defined - Add long-form error message

Make the following methods of `std::net::Ipv6Addr` unstable const under the `const_ipv6` feature: - `segments` - `is_unspecified` - `is_loopback` - `is_global` (unstable) - `is_unique_local` - `is_unicast_link_local_strict` - `is_documentation` - `multicast_scope` - `is_multicast` - `to_ipv4_mapped` - `to_ipv4` Changed the implementation of `is_unspecified` and `is_loopback` to use a `match` instead of `==`. Part of rust-lang#76205
… from `matches!` to `u128` comparison Done because `matches!` doesn't optimize well with array comparisons
Fira Sans is what's used for module lists and other item lists. Previously, the default body font, "Source Serif Pro", was used for crate lists, which didn't visually match other item lists.
Lexer now discerns between regular comments and doc comments, so use that. The change only affects the choice of reported errors.
Add trailing comma support to matches macro

Add more examples to lexicographic cmp on Iterators. Given two arrays of T1 and T2, the most important rule of lexicographical comparison is that two arrays of equal length will be compared until the first difference occured. The examples provided only focuses on the second rule that says that the shorter array will be filled with some T2 that is less than every T1. Which is only possible because of the first rule.

…anic, r=kennytm Move to intra-doc links for library/core/src/panic.rs Helps with rust-lang#75080. @rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc Known issues: * Link from `core` to `std` (rust-lang#74481): [`set_hook`] [`String`]
Make all methods of `std::net::Ipv6Addr` const Make the following methods of `std::net::Ipv6Addr` unstable const under the `const_ipv6` feature: - `segments` - `is_unspecified` - `is_loopback` - `is_global` (unstable) - `is_unique_local` - `is_unicast_link_local_strict` - `is_documentation` - `multicast_scope` - `is_multicast` - `to_ipv4_mapped` - `to_ipv4` This would make all methods of `Ipv6Addr` const. Changed the implementation of `is_unspecified` and `is_loopback` to use a `match` instead of `==`, all other methods did not require a change. All these methods are dependent on `segments`, the current implementation of which requires unstable `const_fn_transmute` ([PR#75085](rust-lang#75085)). Part of rust-lang#76205
