Make shlex available to product and vendor am: bf7615b549 am: 4ed38961a8 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/shlex/+/2476398 Change-Id: I2e0005c3fb182d582354bb0c606b9d34d9d3fa9a Signed-off-by: Automerger Merge Worker <android-build-automerger-merge-worker@system.gserviceaccount.com>
Same idea as (but implementation not directly based on) the Python shlex module. However, this implementation does not support any of the Python module's customization because it makes parsing slower and is fairly useless. You only get the default settings of shlex.split, which mimic the POSIX shell: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html
This implementation also deviates from the Python version in not treating \r specially, which I believe is more compliant.
The algorithms in this crate are oblivious to UTF-8 high bytes, so they iterate over the bytes directly as a micro-optimization.
Disabling the std feature (which is enabled by default) will allow the crate to work in no_std environments, where the alloc crate, and a global allocator, are available.
