Variants (Non-exhaustive)

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LP32

The data model used most commonly on Win16. long and pointer are 32 bits.

ILP32

The data model used most commonly on Win32 and 32-bit Unix systems.

int, long, and pointer are all 32 bits.

LLP64

The data model used most commonly on Win64

long long, and pointer are 64 bits.

LP64

The data model used most commonly on 64-bit Unix systems

long, and pointer are 64 bits.

ILP64

A rare data model used on early 64-bit Unix systems

int, long, and pointer are all 64 bits.
