Detailed Description

A Nix language value, or thunk that may evaluate to a value.

Values are the primary objects manipulated in the Nix language. They are considered to be immutable from a user's perspective, but the process of evaluating a value changes its ValueType if it was a thunk. After a value has been evaluated, its ValueType does not change.

Evaluation in this context refers to the process of evaluating a single value object, also called "forcing" the value; see nix_value_force.

The evaluator manages its own memory, but your use of the C API must follow the reference counting rules.
