Then for any subsequent call of `get_settings()` in the dependencies for the next requests, instead of executing the internal code of `get_settings()` and creating a new `Settings` object, it will return the same object that was returned on the first call, again and again.

## `fastapi run` { #fastapi-run }

Executing `fastapi run` starts FastAPI in production mode by default.

    /** Prefix for queries that search only in title fields. */
    protected static final String ALLINTITLE_FIELD_PREFIX = "allintitle:";

    /** The OpenSearch query builder used for executing the search. */
    protected QueryBuilder queryBuilder;

    /** List of sort builders to apply to the search query. */
    protected final List<SortBuilder<?>> sortBuilderList = new ArrayList<>();

            PrefixQueryCommand newCommand = new PrefixQueryCommand();
            newCommand.register();

            // Verify that the command can process PrefixQuery by executing it
            PrefixQuery query = new PrefixQuery(new Term("field", "test"));
            QueryContext context = new QueryContext("test", false);

            // This should work if the command is properly registered

With the Dependency Injection system, you can also tell **FastAPI** that your *path operation function* also "depends" on something else that should be executed before your *path operation function*, and **FastAPI** will take care of executing it and "injecting" the results.

Other common terms for this same idea of "dependency injection" are:

* resources
* providers
* services
* injectables
* components

## Execution of dependencies with `yield` { #execution-of-dependencies-with-yield }

The sequence of execution is more or less like this diagram. Time flows from top to bottom. And each column is one of the parts interacting or executing code.
