Slices are also present in Python which is similar to slice here in Rust. Slice is used when you do not want the complete collection, or you want some part of it.

WebbRust slices and memory layout As someone migrating from C++ to Rust, I was somewhat confused about how slices are layed out in memory. Because I found it pretty difficult to find this information in the docs, I wrote a blog post about it. Hopefully it's helpful for anyone interacting with the FFI using slices: WebbIterator::find is a function which iterates over an iterator and searches for the first value which satisfies some condition. If none of the values satisfy the condition, it returns None.

"WebbA slice is an unsized type, and therefore can only be used behind a pointer. (String world analogy: str, called string slice, is also unsized.) Arrays get coerced into slices, and vectors can be dereferenced to slices. Therefore, slice methods can be applied to both of them. (String world analogy: str is to String, what [T] is to Vec .)
