Rust – Strings
String data type makes a very important part of any programming language. Rust handles strings a bit differently from other languages.
The String data type in Rust is of two types:
- String Literal (&str)
- String Object (String)
String Literal or &str are called ‘string slices’, which always point to a legitimate UTF-8 sequence. It is used when we know the value of a string at compile time. They are a set of characters and static by default.
Example 1: Declaring string literals.

The String Object is provided by the Standard Library in Rust. It is not a part of the core language and String is heap-allocated, growable, and not null-terminated. They are commonly created by converting them from a string slice by using the to_string() method.
Example 2: Declaring String Object and converting String Literal to String Object

Example 3: Creating an empty string and then set its value.
Rust allows many methods to be used with Strings just as JAVA does. Also, it supports many methods such as indexing, concatenation, and slicing.
