This allows for propagating trait impls on the iterator type.
This is currently only relevant with #![feature(generator_clone)].
The test relied on Error::last_os_error() coming from the stat call on the passed file, but there is no guarantee this will be the case. Instead extract errno from the error returned by the routine. Patch de facto written by joboet. Co-authored-by: joboet <jonasboettiger@icloud.com>
As is the current toy program:
fn main() -> std::io::Result<()> {
use std::fs;
let metadata = fs::metadata("foo.txt")?;
assert!(!metadata.is_dir());
Ok(())
}
... observed under strace will issue:
[snip]
statx(0, NULL, AT_STATX_SYNC_AS_STAT, STATX_ALL, NULL) = -1 EFAULT (Bad address)
statx(AT_FDCWD, "foo.txt", AT_STATX_SYNC_AS_STAT, STATX_ALL, {stx_mask=STATX_ALL|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFREG|0644, stx_size=0, ...}) = 0
While statx is not necessarily always present, checking for it can be
delayed to the first error condition. Said condition may very well never
happen, in which case the check got avoided altogether.
Note this is still suboptimal as there still will be programs issuing
it, but bulk of the problem is removed.
Tested by forbidding the syscall for the binary and observing it
correctly falls back to newfstatat.
While here tidy up the commentary, in particular by denoting some
problems with the current approach.
This commit builds on b72de9b, which removes the `docblock` class from the All Items page, and 9457380, which removes the `docblock` class from the item decl. Fixes rust-lang#92974

…docblock, r=GuillaumeGomez rustdoc: remove `docblock` class from notable trait popover This commit builds on b72de9b, which removes the `docblock` class from the All Items page, and 9457380, which removes the `docblock` class from the item decl. Fixes rust-lang#92974
Allocate one less vec while parsing arrays Probably does not matter, but imo a little bit nicer.
rustdoc: few small cleanups
Remove various double spaces in the libraries. I was just pretty bothered by this when reading the source for a function, and was suggested to check if this happened elsewhere.
