GHC.ExecutionStack.Internal

Contents

Description

Internals of the GHC.ExecutionStack module.

The API of this module is unstable and not meant to be consumed by the general public. If you absolutely must depend on it, make sure to use a tight upper bound, e.g., base < 4.X rather than base < 5, because the interface can change rapidly without much warning.

Since: base-4.9.0.0
