Implement Iterator::last for vec::IntoIter

2025-05-03T03:08:28+00:00

Delegate to inner `vec::IntoIter` from `env::ArgsOs`

2025-05-01T22:18:15+00:00

Delegate from `std::env::ArgsOs` to the methods of the inner platform-specific iterators, when it would be more efficient than just using the default methods of its own impl. Most platforms use `vec::IntoIter` as the inner type, so prioritize delegating to the methods it provides. `std::env::Args` is implemented atop `std::env::ArgsOs` and performs UTF-8 validation with a panic for invalid data. This is a visible effect which users certainly rely on, so we can't skip any arguments. Any further iterator methods would skip some elements, so no change is needed for that type. Add `#[inline]` for any methods which simply wrap the inner iterator.

use generic Atomic type where possible

Also, update the same pattern of reuse in `sys::args` to match.

Rollup merge of #139795 - jethrogb:jb/sgx-linkage-comments, r=joboet

Clarify why SGX code specifies linkage/symbol names for certain statics Specifying linkage/symbol name is solely to ensure a single instance between the `std` crate and its unit tests. Also update the symbol names as items have moved around a bit. The actual name isn't that important, it just needs to be unique. But for debugging it can be useful for it to point to the right place.

Hermit: Unify std::env::args with Unix

2025-04-13T21:35:22+00:00

The only differences between these implementations are that Unix uses relaxed ordering, but Hermit uses acquire/release, and Unix truncates `argv` at the first null pointer, but Hermit doesn't. Since Hermit aims for Unix compatibility, unify it with Unix.
