fi-0025: Imports group must be at top of file {:#fi-0025}

Except for the library declaration at the top of the file, there cannot be any other declarations before the using imports for the file, should they exist:

{% include “docs/reference/fidl/language/error-catalog/label/_bad.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0025.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

To resolve this error, place all of your using imports in a block directly after the library declaration:

{% include “docs/reference/fidl/language/error-catalog/label/_good.md” %}

{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0025.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}

This rule reflects a primarily aesthetic decision by the FIDL team that dependencies are easier to read when they are well-grouped and easily located.
