1.0.0[−][src]Module std::str
Unicode string slices.
See also the str
primitive type.
The &str
type is one of the two main string types, the other being String
.
Unlike its String
counterpart, its contents are borrowed.
Basic Usage
A basic string declaration of &str
type:
let hello_world = "Hello, World!";Run
Here we have declared a string literal, also known as a string slice.
String literals have a static lifetime, which means the string hello_world
is guaranteed to be valid for the duration of the entire program.
We can explicitly specify hello_world
's lifetime as well:
let hello_world: &'static str = "Hello, world!";Run
