…tAddrV6` The following methods are made unstable const under the `const_socketaddr` feature: `SocketAddr` - `ip` - `port` - `is_ipv4` - `is_ipv6` `SocketAddrV4` - `ip` - `port` `SocketAddrV6` - `ip` - `port` - `flowinfo` - `scope_id`
These are currently documented in the API guidelines: https://rust-lang.github.io/api-guidelines/interoperability.html#error-types-are-meaningful-and-well-behaved-c-good-err I think it makes sense to uplift this guideline (in a milder form) into std docs. Printing and producing errors is something that even non-expert users do frequently, so it is useful to give at least some indication of what a typical error message looks like.
Only public items are monomorphization roots. This can be confirmed by noting that this program compiles:
```rust
fn foo<T>() { if true { foo::<Option<T>>() } }
fn bar() { foo::<()>() }
```
I didn't make these renames in rust-lang#80965 because I didn't want the PR to conflict with rust-lang#80914.
I couldn't find any uses of this CSS. I think it was superseded by the `.notable-traits` CSS class and other similarly-named CSS classes.
Constify methods of `std::net::SocketAddr`, `SocketAddrV4` and `SocketAddrV6` The following methods are made unstable const under the `const_socketaddr` feature (rust-lang#82485): ```rust // std::net impl SocketAddr { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; pub const fn is_ipv4(&self) -> bool; pub const fn is_ipv6(&self) -> bool; } impl SocketAddrV4 { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; } impl SocketAddrV6 { pub const fn ip(&self) -> IpAddr; pub const fn port(&self) -> u16; pub const fn flowinfo(&self) -> u32; pub const fn scope_id(&self) -> u32; } ``` Note: `SocketAddrV4::ip` and `SocketAddrV6::ip` use pointer casting and depend on the unstable feature `const_raw_ptr_deref`
…ht, r=GuillaumeGomez rustdoc: Rename internal uses of `spotlight` I didn't make these renames in rust-lang#80965 because I didn't want the PR to conflict with rust-lang#80914.
Document "standard" conventions for error messages These are currently documented in the API guidelines: https://rust-lang.github.io/api-guidelines/interoperability.html#error-types-are-meaningful-and-well-behaved-c-good-err I think it makes sense to uplift this guideline (in a milder form) into std docs.

Monomorphization doc fix
Only public items are monomorphization roots. This can be confirmed by noting that this program compiles:
```rust
fn foo<T>() { if true { foo::<Option<T>>() } }
fn bar() { foo::<()>() }
```

…ochenkov add fp-armv8 for ARM_ALLOWED_FEATURES For fixing err in rust-lang/stdarch#1105.
…petrochenkov Remove nightly features in rustc_type_ir `rustc_type_ir` will be used as a type library by Chalk, which we want to be able to build on stable, so this PR removes the current nightly features used.
