pointer
A single helper, pointer.To(value any) any, that returns a pointer to its argument (and returns the value unchanged if it is already a pointer or interface). Part of rosetta.
What matters here
Tois reflection-based and untyped (anyin,anyout). It exists for cases where the type isn't known at compile time (e.g. building values dynamically for the schema engine). When the type is known, prefer the genericconvert.Pointer[T](v) *T, which is type-safe and avoids reflection —convertowns the generic pointer/dereference helpers (Pointer,Element), not this package.- Already-pointer and interface inputs pass through unchanged, so
Tois idempotent — calling it on a*Treturns the same*T, not a**T.

Overview ¶
Package pointer returns a pointer to a value whose type is not known at compile time.
To is reflection-based and untyped — any in, any out — which is what makes it usable when building values dynamically for the schema engine. Inputs that are already pointers or interfaces pass through unchanged, so To is idempotent and never produces a pointer to a pointer.
When the type is known at compile time, prefer convert.Pointer, which is generic, type-safe, and skips the reflection entirely. The convert package owns the typed pointer helpers; this package exists only for the untyped case.
