[back to package description]

no-value

This package provides the NoValue class for selecting sentinel-like values for each member type. These are 'default' values that are not supposed to represent proper values. They are typically used where you would normally use an error value but cannot. The idea is that they should be recognisable as non-values when encountered in logs or diagnostics.
