2019-10-13Add `dyn` to `Any` documentationCerberuser-5/+5
I noticed that in documentation to `Any` trait the old trait object syntax is used, which could be confusing for newcomers, since we generally recommend using `dyn Trait` instead of just `Trait`. This PR changes the documentation comment, so that it uses `&dyn Any`, `&mut dyn Any` and `Box<dyn Any>`, correspondingly.

2018-07-03Any docs preposition changeEthan McCue-1/+1
This changes the docs referring to where a user should be wary of depending on "Any" trait impls from warning about relying on them "outside" of their code to warning about relying on them "inside" of their code.

2017-03-22Various fixes to wording consistency in the docsStjepan Glavina-1/+1
2017-02-14Auto merge of #38981 - sdleffler:patch-1, r=alexcrichtonbors-1/+5
Add PartialOrd, Ord derivations to TypeId I want to be able to sort a `Vec` of types which contain `TypeId`s, so an `Ord` derivation would be very useful to me. `Hash` and `PartialEq`/`Eq` already exist, so the missing `PartialOrd` and `Ord` derivations feel like an oversight to me.
2017-01-17Add warning about varying hashes/orderingsSean Leffler-0/+4
2017-01-13Change `to_owned` to `to_string` in docsStjepan Glavina-8/+8
We should teach conversion from `str` to `String` using `to_string` rather than the legacy `to_owned`.

2016-03-08doc: Fix a bunch of broken linksAlex Crichton-1/+1
A few categories: * Links into compiler docs were just all removed as we're not generating compiler docs. * Move up one more level to forcibly go to std docs to fix inlined documentation across the facade crates.
2016-01-14Implement Any for unsized typesSteven Fackler-1/+1
This is a bit weird since unsized types can't be used in trait objects, but Any is *also* used as pure marker trait since Reflect isn't stable. There are many cases (e.g. TypeMap) where all you need is a TypeId.

2015-08-15core: Fill out issues for unstable featuresAlex Crichton-1/+2
2015-08-09Replace many uses of `mem::transmute` with more specific functionsTobias Bucher-2/+2
The replacements are functions that usually use a single `mem::transmute` in their body and restrict input and output via more concrete types than `T` and `U`. Worth noting are the `transmute` functions for slices and the `from_utf8*` family for mutable slices. Additionally, `mem::transmute` was often used for casting raw pointers, when you can already cast raw pointers just fine with `as`.

2015-06-17core: Split apart the global `core` featureAlex Crichton-1/+1
This commit shards the broad `core` feature of the libcore library into finer grained features. This split groups together similar APIs and enables tracking each API separately, giving a better sense of where each feature is within the stabilization process. A few minor APIs were deprecated along the way: * Iterator::reverse_in_place * marker::NoCopy
2015-04-30Add downcasting to std::error::ErrorAaron Turon-4/+2
This commit brings the `Error` trait in line with the [Error interoperation RFC](https://github.com/rust-lang/rfcs/pull/201) by adding downcasting, which has long been intended. This change means that for any `Error` trait objects that are `'static`, you can downcast to concrete error types. To make this work, it is necessary for `Error` to inherit from `Reflect` (which is currently used to mark concrete types as "permitted for reflection, aka downcasting"). This is a breaking change: it means that impls like ```rust impl<T> Error for MyErrorType<T> { ... } ``` must change to something like ```rust impl<T: Reflect> Error for MyErrorType<T> { ... } ``` except that `Reflect` is currently unstable (and should remain so for the time being). For now, code can instead bound by `Any`: ```rust impl<T: Any> Error for MyErrorType<T> { ... } ``` which *is* stable and has `Reflect` as a super trait. The downside is that this imposes a `'static` constraint, but that only constrains *when* `Error` is implemented -- it does not actually constrain the types that can implement `Error`.

2015-04-01Fallout in libstd: remove impls now considered to conflict.Niko Matsakis-0/+8
2015-03-30std: Stabilize the rest of Any/BoxAnyAlex Crichton-2/+1
This commit stabilizes the following APIs: * `TypeId::of` - now that it has an `Any` bound it's ready to be stable. * `Box<Any>::downcast` - now that an inherent impl on `Box<Any>` as well as `Box<Any+Send>` is allowed the `BoxAny` trait is removed in favor of these inherent methods. This is a breaking change due to the removal of the `BoxAny` trait, but consumers can simply remove imports to fix crates. [breaking-change]
2015-03-26Implement `Reflect` trait with a variant on the standard OIBITNiko Matsakis-11/+13
semantics that tests the *interface* of trait objects, rather than what they close over.
