Use

use statement is used to import functions from standard library “package” into the current scope, so we can use the functions directly.

INFO

Unlike Navi's package, in Navi Stream, all of the stdlib has been default imported, so you can use them directly with out use.

With use

When using the use statement to import a namespace, we can directly use the ma function, as well as all functions in ta:

use ta;

let avg = ma(value, 10);

You also can import multiple packages at once:

use ta, quote, math;

let avg = abs(-1);
// avg = 1

Without use

By default, we can use <package>.<fn> to call functions in the standard library without using use. For example, the following statement calls the ma function in the ta namespace.

let avg = ta.ma(value, 10);
