Package kotlin

class DeepRecursiveFunction<T, R>(block: suspend DeepRecursiveScope<T, R>.(T) -> R)

Defines deep recursive function that keeps its stack on the heap, which allows very deep recursive computations that do not use the actual call stack. To initiate a call to this deep recursive function use its invoke function. As a rule of thumb, it should be used if recursion goes deeper than a thousand calls.

DeepRecursiveScope

sealed class DeepRecursiveScope<T, R>

DeprecatedSinceKotlin

annotation class DeprecatedSinceKotlin(warningSince: String, errorSince: String, hiddenSince: String)

Marks the annotated declaration as deprecated. In contrast to Deprecated, severity of the reported diagnostic is not a constant value, but differs depending on the API version of the usage (the value of the -api-version argument when compiling the module where the usage is located). If the API version is greater or equal than hiddenSince, the declaration will not be accessible from the code (as if it was deprecated with level DeprecationLevel.HIDDEN), otherwise if the API version is greater or equal than errorSince, the usage will be marked as an error (as with DeprecationLevel.ERROR), otherwise if the API version is greater or equal than warningSince, the usage will be marked as a warning (as with DeprecationLevel.WARNING), otherwise the annotation is ignored.
