 # Vectors and strings
 
-A vector is a contiguous section of memory containing zero or more
-values of the same type. Like other types in Rust, vectors can be
-stored on the stack, the local heap, or the exchange heap. Borrowed
-pointers to vectors are also called 'slices'.
+A vector is a contiguous block of memory containing zero or more values of the
+same type. Rust also supports vector reference types, called slices, which are
+a view into a block of memory represented as a pointer and a length.
+
+Strings are represented as vectors of `u8`, with the guarantee of containing a
+valid UTF-8 sequence.
+
+Fixed-size vectors are an unboxed block of memory, with the element length as
+part of the type. A fixed-size vector owns the elements it contains, so the
+elements are mutable if the vector is mutable. Fixed-size strings do not exist.

-The `+` operator means concatenation when applied to vector types.

+allocated memory on the heap. A unique vector owns the elements it contains, so

-> ***Note:*** The above examples of vector addition use owned

+Slices are similar to fixed-size vectors, but the length is not part of the
+type. They simply point into a block of memory and do not have ownership over

+// An unadorned string literal is an immutable string slice
+let string = "foobar";
+
+// A string slice type is written as &str
+let view: &str = string.slice(0, 3);
+~~~
+
+Mutable slices also exist, just as there are mutable references. However, there
+are no mutable string slices. Strings are a multi-byte encoding (UTF-8) of
+Unicode code points, so they cannot be freely mutated without the ability to
+alter the length.
