Enum Certainty 

pub enum Certainty {
    Certain,
    Conditional(String),
    Unknown(String),
}

Certainty attached to a node that exists but may be conditional.

Distinct from Resolved: that answers “did the lookup succeed”, this answers “does this thing definitely exist at runtime”.

Variants

Certain

Unconditionally present.

Conditional(String)

Present only under a condition the analyzer could not evaluate (a config-dependent bias, an Option field, a branch).

Unknown(String)

The analyzer could not model the construct at all; reported so the hole is visible.
