data NAtom

Atoms are values that evaluate to themselves. This means that they appear in both the parsed AST (in the form of literals) and the evaluated form.

Constructors

NURI Text

An URI like https://example.com.

NInt Integer

An integer. The c nix implementation currently only supports integers that fit in the range of Int64.

NFloat Float

A floating point number

NBool Bool

Booleans. false or true.

NNull

Null values. There's only one of this variant: null.
