Use for_each to extend collections

2019-04-05T21:51:07+00:00

This updates the `Extend` implementations to use `for_each` for many collections: `BinaryHeap`, `BTreeMap`, `BTreeSet`, `LinkedList`, `Path`, `TokenStream`, `VecDeque`, and `Wtf8Buf`. Folding with `for_each` enables better performance than a `for`-loop for some iterators, especially if they can just forward to internal iterators, like `Chain` and `FlatMap` do.

Mark unix::ffi::OsStrExt methods as inline This is a small change, but I found it surprising it's not inlined looking at the assembly.

wasi: Implement more of the standard library This commit fills out more of the `wasm32-unknown-wasi` target's standard library, notably the `std::fs` module and all of its internals. A few tweaks were made along the way to non-`fs` modules, but the last commit contains the bulk of the work which is to wire up all APIs to their equivalent on WASI targets instead of unconditionally returning "unsupported". After this some basic filesystem operations and such should all be working in WASI!

wasi: Fill out `std::fs` module for WASI

2019-04-03T15:05:46+00:00

This commit fills out the `std::fs` module and implementation for WASI. Not all APIs are implemented, such as permissions-related ones and `canonicalize`, but all others APIs have been implemented and very lightly tested so far. We'll eventually want to run a more exhaustive test suite! For now the highlights of this commit are: * The `std::fs::File` type is now backed by `WasiFd`, a raw WASI file descriptor. * All APIs in `std::fs` (except permissions/canonicalize) have implementations for the WASI target. * A suite of unstable extension traits were added to `std::os::wasi::fs`. These traits expose the raw filesystem functionality of WASI, namely `*at` syscalls (opening a file relative to an already opened one, for example). Additionally metadata only available on wasi is exposed through these traits. Perhaps one of the most notable parts is the implementation of path-taking APIs. WASI actually has no fundamental API that just takes a path, but rather everything is relative to a previously opened file descriptor. To allow existing APIs to work (that only take a path) WASI has a few syscalls to learn about "pre opened" file descriptors by the runtime. We use these to build a map of existing directory names to file descriptors, and then when using a path we try to anchor it at an already-opened file. This support is very rudimentary though and is intended to be shared with C since it's likely to be so tricky. For now though the C library doesn't expose quite an API for us to use, so we implement it for now and will swap it out as soon as one is available.
