Struct Trace 

Source 
pub struct Trace {
    pub context: Vec<Frame>,
    pub expectation: Expectation,
}
Expand description

One recorded parse attempt at Error::pos — a rule call chain and what it expected to find there. Multiple Traces at the same position are candidates: any one of them matching would have let the parse continue.

Fields§

§context: Vec<Frame>

The nearest enclosing named rule(s), outermost first. Only ever more than one element with trace_all_nodes enabled.

§expectation: Expectation

What was expected at this position.
