This feature is intended to provide expensive but thorough help for developers who have an unexpected `TypeId` value and need to determine what type it actually is. It causes `impl Debug for TypeId` to print the type name in addition to the opaque ID hash, and in order to do so, adds a name field to `TypeId`. The cost of this is the increased size of `TypeId` and the need to store type names in the binary; therefore, it is an optional feature. It may be enabled via `cargo -Zbuild-std -Zbuild-std-features=debug_typeid`. (Note that `-Zbuild-std-features` disables default features which you may wish to reenable in addition; see <https://doc.rust-lang.org/cargo/reference/unstable.html#build-std-features>.) Example usage and output: ``` fn main() { use std::any::{Any, TypeId}; dbg!(TypeId::of::<usize>(), drop::<usize>.type_id()); } ``` ``` TypeId::of::<usize>() = TypeId(0x763d199bccd319899208909ed1a860c6 = usize) drop::<usize>.type_id() = TypeId(0xe6a34bd13f8c92dd47806da07b8cca9a = core::mem::drop<usize>) ``` Also added feature declarations for the existing `debug_refcell` feature so it is usable from the `rust.std-features` option of `config.toml`.
Adds `const` `Ip*Addr::as_octets` methods providing reference access to `Ip*Addr` octets contents. See rust-lang/libs-team#535 for accepted ACP with a more detailed justification.
Continuing the work from rust-lang#137162. Every method gains a `hir_` prefix.

Optionally add type names to `TypeId`s. This feature is intended to provide expensive but thorough help for developers who have an unexpected `TypeId` value and need to determine what type it actually is. It causes `impl Debug for TypeId` to print the type name in addition to the opaque ID hash, and in order to do so, adds a name field to `TypeId`. The cost of this is the increased size of `TypeId` and the need to store type names in the binary; therefore, it is an optional feature. It does not expose any new public API, only change the `Debug` implementation. It may be enabled via `cargo -Zbuild-std -Zbuild-std-features=debug_typeid`. (Note that `-Zbuild-std-features` disables default features which you may wish to reenable in addition; see <https://doc.rust-lang.org/cargo/reference/unstable.html#build-std-features>.) Example usage and output: ``` fn main() { use std::any::{Any, TypeId}; dbg!(TypeId::of::<usize>(), drop::<usize>.type_id()); } ``` ``` TypeId::of::<usize>() = TypeId(0x763d199bccd319899208909ed1a860c6 = usize) drop::<usize>.type_id() = TypeId(0xe6a34bd13f8c92dd47806da07b8cca9a = core::mem::drop<usize>) ``` Also added feature declarations for the existing `debug_refcell` feature so it is usable from the `rust.std-features` option of `config.toml`.

libcore/net: `IpAddr::as_octets()` [ACP](rust-lang/libs-team#535) [Tracking issue](rust-lang#137259) Adds `const` `core::net::IpAddr{,v4,v6}::as_octets()` methods to provide reference access to IP address contents. The concrete usecase for me is allowing the `IpAddr` to provide an extended lifetime in contexts that want a `&[u8]`: ```rust trait AddrSlice { fn addr_slice(&self) -> &[u8]; } impl AddrSlice for IpAddrV4 { fn addr_slice(&self) -> &[u8] { // self.octets() doesn't help us here, because we can't return a reference to the owned array. // Instead we want the IpAddrV4 to continue owning the memory: self.as_octets() } } ``` (Notably, in this case we can't parameterize `AddrSlice` by a `const N: usize` (such that `fn addr_slice(&self) -> [u8; N]`) and maintain object-safety.)
…r=tgross35 Stabilise `os_str_display` Closes rust-lang#120048.
Move methods from Map to TyCtxt, part 3. A follow-up to rust-lang#137162. r? `@Zalathar`
…si-stdin, r=alexcrichton Implement `read_buf` for WASI stdin `WasiFd::read_buf` already exists. Simply use it in `Stdin`. cc `@alexcrichton` Tracked in rust-lang#136756
…errors Refactor `OperandRef::extract_field` to prep for MCP838 cc rust-lang/compiler-team#838 This still supports exactly the same cases as it did before, just rearranged a bit to better emphasize what doesn't work.
…r=jieyouxu Do not exempt nonexistent platforms from platform policy In rust-lang#137324 I approved the change of the i586-pc-qnx platform to i686 with this extra line included. I noticed it but thought it was a bootstrap problem of some sort. Nonetheless, removing this line doesn't seem to change anything. r? `@Noratrieb`
…_case, r=compiler-errors Stacker now handles miri using a noop impl itself Reverts a no longer necessary change from rust-lang#136580.
