Struct TraceStep 

pub struct TraceStep {
    pub atom: String,
    pub value: Value,
    pub reason: TraceReason,
}

One link in a Conflict’s derivation chain: an atom, the value it was forced to, and why it holds that value.

Fields

atom: String

Human label of the atom (subject predicate [object]).

value: Value

The confident value the atom was forced to (TRUE or FALSE).

reason: TraceReason

Why the atom holds that value.

Trait Implementations

impl Clone for TraceStep

fn clone(&self) -> TraceStep

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TraceStep

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TraceStep

impl PartialEq for TraceStep

fn eq(&self, other: &TraceStep) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
