Types

Developer notes for include/stratax/core/Types.hpp.

Purpose

Defines stable dtype aliases used across Stratax.

Main API

Boolean

• bool_

Integers

• int8, int16, int32, int64
• uint8, uint16, uint32, uint64

Floating Point

• float32
• float64
• float128

Complex

• complex64
• complex128
• complex256

Indexing

• index_t
• ssize_t

Invariants

• Type aliases map directly to standard C++ types.
• Aliases do not own storage and do not encode runtime metadata.
• Whether an alias is accepted as numeric is controlled by Concepts.hpp.

Validation Notes

• These are aliases only.
• Acceptance as a container dtype is controlled by Concepts.hpp.
• int8 and uint8 may be excluded by numeric concepts because they alias char-like types.

Implementation Notes

• Keep aliases mapped directly to standard C++ types.
• Avoid hiding ownership or storage policy in this file.

Time Complexity

• Type aliases have no runtime cost.
• Any acceptance or rejection of aliases is handled at compile time by Concepts.hpp.

Future Work

• Add dtype traits.
• Add dtype promotion rules.
• Add dtype name/string helpers.
• Revisit float128 portability.
