Internal Libraries

A library is internal to a project if it is in the same source src directory as the other program files.

$ tree
.
├── Cargo.toml
├── Forc.toml
└── src
    ├── lib.sw
    └── my_library.sw

To be able to use our library my_library.sw in lib.sw there are two steps to take:

1. Bring our library into scope by using the mod keyword followed by the library name
2. Use the use keyword to selectively import various items from the library

library;

mod my_library;

use my_library::bar;

// `bar` from `my_library` is now available throughout the file
