rust-index: slicechunktodensity returns Rust result
Ready for removal of the scaffolding.
This time, we allow ourselves a minor optimization: we avoid
allocating for each chunk. Instead, we reuse the same vector,
and perform at most one allocation per chunk.
The `PyList` constructor will copy the buffer anyway.
{
// Enforcing
"eqeqeq" : true, // true: Require triple equals (===) for comparison
"forin" : true, // true: Require filtering for..in loops with obj.hasOwnProperty()
"freeze" : true, // true: prohibits overwriting prototypes of native objects such as Array, Date etc.
"nonbsp" : true, // true: Prohibit "non-breaking whitespace" characters.
"undef" : true, // true: Require all non-global variables to be declared (prevents global leaks)
// Environments
"browser" : true // Web Browser (window, document, etc)
