A.18.1 The Package Containers
The package Containers is the root of the containers
subsystem.
Static Semantics
The library package
Containers has the following declaration:
package Ada.Containers
with Pure
is
type Hash_Type
is mod implementation-defined;
type Count_Type
is range 0 ..
implementation-defined;
Capacity_Error :
exception;
end Ada.Containers;
Hash_Type represents the range of the result of a
hash function. Count_Type represents the (potential or actual) number
of elements of a container.
Capacity_Error is raised when the capacity of a
container is exceeded.
Implementation Advice
Hash_Type'Modulus should be at least 2**32. Count_Type'Last
should be at least 2**31–1.
