Modules and Visibility

Flint keeps the module system intentionally small.

One File, One Module

Each file is a module. The filename defines the module name. There is no separate module declaration.

Imports

Use use for imports:

use json
use micro/gpio
use ./board
use ./drivers/sensor

The rule is simple:

• bare paths are for standard library modules,
• ./ paths are for local modules in the current project.

Visibility

Flint has two visibility levels:

• pub
• private by default

There is no larger visibility ladder to memorize.
