Module nom::lib::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!";

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!";
