There're still faster approaches than naïve and probably common "copy valid byte sequences one by one into a resizable result buffer". For instance, scan through the input bytes all at once, keeping track of position and length of valid sequences, then memcopy each valid sequence into a preallocated buffer.

Edit: Although, it looks like Rust's std already does this, except for preallocating an exactly correct size result buffer: https://doc.rust-lang.org/src/alloc/string.rs.html#538

It didn't. Rather, it didn't until after it had been conduct.
