Futhark.FreshNames

Description

This module provides facilities for generating unique names.

Synopsis

data VNameSource
blankNameSource :: VNameSource
newNameSource :: Int -> VNameSource
newName :: VNameSource -> VName -> (VName, VNameSource)
newVName :: VNameSource -> String -> (VName, VNameSource)
newVNameFromName :: VNameSource -> Name -> (VName, VNameSource)

Documentation

data VNameSource Source #

A name source is conceptually an infinite sequence of names with no repeating entries. In practice, when asked for a name, the name source will return the name along with a new name source, which should then be used in place of the original.

The Ord instance is based on how many names have been extracted from the name source.
