Attributes, Specifiers, and Effects

public |
The identifier is universally accessible. You can use this on modules, classes, interfaces, structs, enums, methods, and data. |
Effects
The following effects determine how Sgn behaves in your programs. For the complete list of effects, see the Effect Specifers section of the Specifiers Page.
| Effect | Meaning |
|---|---|
computes |
This effect requires that the function has no side effects, and is not guaranteed to complete. There's an unchecked requirement that the function, when provided with the same arguments, produces the same result. Any function that doesn't have the native specifier that would otherwise have the converges effect is a good example of using the computes effect. |
