Detailed Description

This module contains the derived types for generating allocatable containers of scalar, vector, matrix, or cube of integer, real, complex, logical, and string values of arbitrary kinds.

This module offer two broad categories of container derived types:

1. containers that end with \(\ms{*_type}\) are derived type containers of intrinsic types of default kind: SK, IK, LK, CK, RK.
   
2. containers that end with \(\ms{*_pdt}\) are parameterized derived type containers of intrinsic types of arbitrary kind.
   

Each of the above categories contains the following subcategories based on their component (val) rank:

1. containers that end with \(\ms{*_type}\) are derived type containers of intrinsic types of default kind: SK, IK, LK, CK, RK.
   
2. containers that end with \(\ms{*_pdt}\) are parameterized derived type containers of intrinsic types of arbitrary kind type parameter.
   

Naming convention

The containers of this module use a concise letter-based naming convention:

1. The first letter in all container names \(\ms{c**_type}\) or \(\ms{c**_pdt}\) stands for container.
   
2. The second letter in all container names \(\ms{*x*_type}\) or \(\ms{*x*_pdt}\) stands for the rank of the component of the container:
   
   1. The letter \(\ms{s}\) as in \(\ms{*s*_type}\) or \(\ms{*s*_pdt}\) stands for a scalar-component container (container%val).
      
   2. The letter \(\ms{v}\) as in \(\ms{*v*_type}\) or \(\ms{*v*_pdt}\) stands for a vector-component container (container%val(:)).
      
   3. The letter \(\ms{m}\) as in \(\ms{*m*_type}\) or \(\ms{*m*_pdt}\) stands for a matrix-component container (container%val(:,:)).
      
   4. The letter \(\ms{c}\) as in \(\ms{*c*_type}\) or \(\ms{*c*_pdt}\) stands for a cube-component container (container%val(:,:,:)).
      
3. The third letter in all container names \(\ms{**x_type}\) or \(\ms{**x_pdt}\) stands for the type of the component of the container:
   
   1. The letter \(\ms{s}\) as in \(\ms{**s_type}\) or \(\ms{**s_pdt}\) stands for a string-component (character) container.
      
   2. The letter \(\ms{i}\) as in \(\ms{**i_type}\) or \(\ms{**i_pdt}\) stands for a integer-component container.
      
   3. The letter \(\ms{l}\) as in \(\ms{**l_type}\) or \(\ms{**l_pdt}\) stands for a logical-component container.
      
   4. The letter \(\ms{c}\) as in \(\ms{**c_type}\) or \(\ms{**c_pdt}\) stands for a complex-component container.
      
   5. The letter \(\ms{r}\) as in \(\ms{**r_type}\) or \(\ms{**r_pdt}\) stands for a real-component container.
      
4. The final suffix \(\ms{***_type}\) and \(\ms{***_pdt}\) stand for the derived type and Parameterized Derived Type (PDT) containers.
   

For example:

1. Read css_type as container of scalar of string (character) derived type (of default kind SK). This container is widely known as varying string or simply string in the Fortran community.
   
2. Read css_pdt as container of scalar of string (character) derived type (of kind any supported by the processor (e.g., SK, SKA, SKD , or SKU)). This container is widely known as varying string or simply string in the Fortran community.
   
3. Read csi_type as container of scalar of integer derived type (of default kind IK).
4. Read cvr_type as container of vector of real derived type (of default kind RK).

What is the use of containers?

Containers are essential for creating jagged arrays.
While string containers are the most popular container type in almost all languages, other container types and ranks offered by this module find heavy use in Machine Learning and Data Science or even simple computational tasks.

Warning

The elemental versions of the generic interfaces of this procedure are known to yield incorrect result if compiled by gfortran version 10-12.
The Intel Fortran compiler yields the correct elemental results.

Developer Remark:

Currently, only the scalar containers (matching names \(\ms{cs*_pdt}\) and \(\ms{cs*_type}\)) have custom elemental constructors.
The was no perceived usage and consensus on how to design custom constructors for containers of higher-rank components (e.g., vector, matrix, and cube containers).

Todo:

Normal Priority: Currently, only the following containers are exemplified:

1. css_pdt
   
2. css_type
   

Examples for the following generic interfaces must be added:

1. csi_pdt
   
2. csl_pdt
   
3. csc_pdt
   
4. csr_pdt
   
5. csi_type
   
6. csl_type
