Package: Ada.Strings.Search

Dependencies

with Ada.Strings.Maps;

Description

This package contains the search functions from Ada.Strings.Fixed. They are separated out because they are shared by Ada.Strings.Bounded and Ada.Strings.Unbounded, and we don't want to drag other irrelevant stuff from Ada.Strings.Fixed when using the other two packages. We make this a private package, since user programs should access these subprograms via one of the standard string packages.
