gc-safe-value[t] t() unsafe

Returns an arbitrary value of the type. The main use of this is to overwrite unused values in a buffer, to free the memory.

reference-equal[t] bool(a t, b t) unsafe

True if two values are considered exactly equal. In a Java build, this is like the '==' operator from Java. In a JS build, this uses '===' for most types or 'Object.is' for floats (to ensure NaN equals itself).

reinterpret-cast[output, input] output(a input) unsafe

Treat an input as if it were an output. WARN: Use only if you're sure an input can be treated as an output. Otherwise this could cause invalid bytecode to be generated.

safe-reinterpret-cast char8[](a nat8[])

Certain reinterpret-casts are guaranteed to be safe. For example, treating signed integers as unsigned integers wraps based on two's complement.

weak-ref[t] builtin

new[t] t weak-ref() unsafe

Create an already-expired reference (weak-refs are intrinsically optional)

new[t] t weak-ref(a t) unsafe

get[t] t option(a t weak-ref) unsafe
