Enum ValueStore 

Source 
pub enum ValueStore<T> {
    Value(T),
    NoValue {
        message: String,
    },
}
Expand description

A single plain value for one property, or a no-value with the reason.

This is the unit kept in IpIntelligenceDataBase’s plain typed stores. It mirrors the two states of an AspectPropertyValue: a present value, or a no-value message explaining why the engine determined nothing.

Variants§

§

Value(T)

A present value.

§

NoValue

No value could be determined. The message explains why.

Fields

§message: String

The explanation surfaced through the accessor when read.
