What does use crate::body::Body; mean?

Question

On https://github.com/sdroege/rtsp-server/blob/master/src/listener/message_socket.rs, it does

use crate::body::Body;

I could only find information about external crates: https://doc.rust-lang.org/reference/items/extern-crates.html

What does use crate:: mean?

Answer 1

It refers to to the crate currently being compiled. So in this example, it is resolved as rtsp_server::body::Body. The body::Body part is refering to the Body item in the body module.

The Rust documentation says:

crate is also used to represent the absolute path of a module, where crate refers to the root of the current crate. For instance, crate::foo::bar refers to the name bar inside the module foo, from anywhere else in the same crate.
