This package provides the type DataValue
that is used to represent missing data.
Currently the main use of this type is in the Query.jl and IterableTables.jl packages.
This repo is based on the following principles/ideas:
DataValue
arguments.&
and |
operators follow the 3VLDataValue
s.==
, <
etc. on DataValue
s returnBool
values, i.e. they are normal predicates.DataValue
either via theget(x)
function, or use the x[]
syntax.Any help with this package would be greatly appreciated!
