SIFR-META-0002: Package const specialization reported a hard warning. - Sifr

SIFR-META-0002 belongs to the Package metaprogramming diagnostic family. It means: package const specialization reported a hard warning.

Why It Happens

Deterministic package specialization either reported a bounded issue or declared issue data that does not match its compiler-checked template. Fix the static schema input or the package issue declaration named by the diagnostic.

Use sifr --explain SIFR-META-0002 locally to see the renderer’s exact message template and any machine-applicable suggestions for the compiler version you are running.

Erroneous Code

@const_specialize
def describe[T]() -> ConstSpecializationOutcome[str]:
    return produced_with_warning("shape", "shape.deprecated", {})

How To Fix It

Update the static declaration identified by the package warning. Const-specialization warnings are hard compiler warnings and are intentionally not lint suppressions.

Fixed Code

@const_specialize
def describe[T]() -> ConstSpecializationOutcome[str]:
    return produced("shape")
