Provide map_ok and map_err method for Poll<Option<Result<T, E>>> Currently `map_ok` and `map_err` methods are given for `Poll<Result<T, E>>`. This PR adds these methods for `Poll<Option<Result<T, E>>>` as they are helpful in stream building code.

2019-08-14Rollup merge of #63421 - clarfon:escape_default, r=dtolnayMazdak Farrokhzad-0/+9
Implement Clone, Display for ascii::EscapeDefault This will mimic the same behaviour as the `char` version; `Display`ing the iterator will give its string representation without advancing it.

2019-08-12Reduce the genericity of closures in the iterator traitsJosh Stone-80/+194
By default, closures inherit the generic parameters of their scope, including `Self`. However, in most cases, the closures used to implement iterators don't need to be generic on the iterator type, only its `Item` type. We can reduce this genericity by redirecting such closures through local functions. This does make the closures more cumbersome to write, but it will hopefully reduce duplication in their monomorphizations, as well as their related type lengths.

2019-08-11Rollup merge of #63346 - RalfJung:zeroed-lint, r=eddybMark Rousskov-1/+5
Lint on some incorrect uses of mem::zeroed / mem::uninitialized Cc https://github.com/rust-lang/rust/issues/62825 and https://internals.rust-lang.org/t/make-mem-uninitialized-and-mem-zeroed-panic-for-some-types-where-0-is-a-niche/10605 This does not yet handle `NonNull`/`NonZero*`, but it is a start. I also improved some doc issues I hit on the way, and added a useful helper to `TyS`. EDIT: I added the relnotes label mostly as a proposal -- I think this is worth mentioning, but leave the decision up to the release team.

Give built-in macros stable addresses in the standard library Continuation of https://github.com/rust-lang/rust/pull/62086. Derive macros corresponding to traits from libcore are now available through the same paths as those traits: - `Clone` - `{core,std}::clone::Clone` - `PartialEq` - `{core,std}::cmp::PartialEq` - `Eq` - `{core,std}::cmp::Eq` - `PartialOrd` - `{core,std}::cmp::PartialOrd` - `Ord` - `{core,std}::cmp::Ord` - `Default` - `{core,std}::default::Default` - `Debug` - `{core,std}::fmt::Debug` - `Hash` - `{core,std}::hash::Hash` - `Copy` - `{core,std}::marker::Copy` Fn-like built-in macros are now available through libcore and libstd's root module, by analogy with non-builtin macros defined by libcore and libstd: ```rust {core,std}::{ __rust_unstable_column, asm, assert, cfg, column, compile_error, concat, concat_idents, env, file, format_args, format_args_nl, global_asm, include, include_bytes, include_str, line, log_syntax, module_path, option_env, stringify, trace_macros, } ``` Derive macros without a corresponding trait in libcore or libstd are still available only through prelude (also see https://github.com/rust-lang/rust/pull/62507). Attribute macros also keep being available only through prelude, mostly because they don't have an existing practice to follow. An advice from the library team on their eventual placement would be appreciated. ```rust RustcDecodable, RustcEncodable, bench, global_allocator, test, test_case, ``` r? @alexcrichton

Remove gensym in format_args This also fixes some things to allow us to export opaque macros from libcore: * Don't consider items that are only reachable through opaque macros as public/exported (so they aren't linted as needing docs) * Mark private items reachable from the root of libcore as unstable - they are now reachable (in principle) in other crates via macros in libcore r? @petrochenkov
