Attributes and Effects

The following attributes and effects determine how IsFinite behaves and how you can use it in your programs. For the complete list of attribute and effect specifiers, see the Specifiers Page.

Attribute	Meaning
`native`	Indicates that the definition details of the element are implemented in C++. Verse definitions with the `native` specifier auto-generate C++ definitions that a developer can then fill out its implementation. You can use this specifier on classes, interfaces, enums, methods, and data.
`public`	The identifier is universally accessible. You can use this on modules, classes, interfaces, structs, enums, methods, and data.

Effect Meaning

decides Indicates that the function can fail, and that calling this function is a failable expression. Function definitions with the decides effect must also have the transacts effect, which means the actions performed by this function can be rolled back (as if the actions were never performed), if there’s a failure anywhere in the function.

converges This effect guarantees that not only is there no side effect from the execution of the related function, but that the function definitely completes (does not infinitely recurse). This effect can only appear in functions that have the native specifer, but this isn’t checked by the compiler. Code that is used to provide default values of class or values for global variables are required to have this effect. The functions sin(), cos(), and tan() are examples of functions that have the converges effect.

Effect	Meaning
`decides`	Indicates that the function can fail, and that calling this function is a failable expression. Function definitions with the `decides` effect must also have the `transacts` effect, which means the actions performed by this function can be rolled back (as if the actions were never performed), if there’s a failure anywhere in the function.
`converges`	This effect guarantees that not only is there no side effect from the execution of the related function, but that the function definitely completes (does not infinitely recurse). This effect can only appear in functions that have the `native` specifer, but this isn’t checked by the compiler. Code that is used to provide default values of class or values for global variables are required to have this effect. The functions `sin()`, `cos()`, and `tan()` are examples of functions that have the `converges` effect.
