`TwistAxis`

Select the axis along which a twist deformation is applied.

Why this exists

A raw integer or string axis specifier would allow out-of-range values that are only caught at runtime. TwistAxis restricts callers to exactly three valid choices — X, Y, or Z — enforcing correctness at compile time. As a scoped enum class, it prevents silent implicit conversion to int, making axis-passing code self-documenting and type-safe.

Fields

Name	Type	Description
`X`	enumerator	The X axis.
`Y`	enumerator	The Y axis.
`Z`	enumerator	The Z axis.

Construction

// Apply twist along the Y axis
dna::TwistAxis axis = dna::TwistAxis::Y;

Constraints

Exactly three valid values: X, Y, Z.
Scoped enum class — implicit conversion to int is not allowed; use static_cast<int> if an integer representation is required.
