/* Mangled Rust symbols look like this:
_$LT$std..sys..fd..FileDesc$u20$as$u20$core..ops..Drop$GT$::drop::hc68340e1baa4987a
The original symbol is:
<std::sys::fd::FileDesc as core::ops::Drop>::drop
The last component of the path is a 64-bit hash in lowercase hex,
prefixed with "h". Rust does not have a global namespace between
crates, an illusion which Rust maintains by using the hash to
distinguish things that would otherwise have the same symbol.
Any path component not starting with a XID_Start character is
prefixed with "_".
The following escape sequences are used:
"," => $C$
"@" => $SP$
"*" => $BP$
"&" => $RF$
"<" => $LT$
">" => $GT$
"(" => $LP$
")" => $RP$
" " => $u20$
"\"" => $u22$
"'" => $u27$
"+" => $u2b$
";" => $u3b$
"[" => $u5b$
"]" => $u5d$
"{" => $u7b$
"}" => $u7d$
"~" => $u7e$
A double ".." means "::" and a single "." means "-".

This function looks for the following indicators:
1. The hash must consist of "h" followed by 16 lowercase hex digits.
2. As a sanity check, the hash must use between 5 and 15 of the 16
possible hex digits. This is true of 99.9998% of hashes so once
in your life you may see a false negative. The point is to
notice path components that could be Rust hashes but are
probably not, like "haaaaaaaaaaaaaaaa". In this case a false
positive (non-Rust symbol has an important path component
removed because it looks like a Rust hash) is worse than a false
negative (the rare Rust symbol is not demangled) so this sets
the balance in favor of false negatives.
3. There must be no characters other than a-zA-Z0-9 and _.:$
4. There must be no unrecognized $-sign sequences.
5. There must be no sequence of three or more dots in a row ("..."). */
