Struct GuardTrace 

pub struct GuardTrace {
    pub desc: String,
    pub holds: bool,
    pub children: Vec<GuardTrace>,
}

A Guard evaluated to a truth tree: each predicate node with its prose description and whether it currently holds. Serializable, so a devtool can render exactly which atom a stuck step is waiting on.

Fields

desc: String

Prose description of this node (from Guard::describe vocabulary).

holds: bool

Whether this node currently holds.

children: Vec<GuardTrace>

Operand traces for all/any/not; empty for atoms.
