Rust is now overall faster than C in benchmarks

D uses slices for strings, which also gives D a big performance boost over C whenever strings are in play.

Walter, can you elaborate on this, are D's slices functionally equivalent to C++'s string_view? I.e. no copying as long no 'ASCIIZ-dependent' code is involved?

D strings are a simply a pointer/length pair. Substrings can be extracted with no alloc/copying necessary. The length can be determined without loading the string into the cache and scanning it.

Those two features make for big speed improvements.
