Make shlex available to product and vendor Bug: 270690570 Test: mma in external/rust/crates Change-Id: If10cc8865d79293404dd5d133d05943478935c47
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.
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.
