Enum CovTerm

Source 
pub enum CovTerm {
    Zero,
    Counter(CounterId),
    Expression(ExpressionId),
}
Expand description

Enum that can hold a constant zero value, the ID of an physical coverage counter, or the ID of a coverage-counter expression.

This was originally only used for expression operands (and named Operand), but the zero/counter/expression distinction is also useful for representing the value of code/gap mappings, and the true/false arms of branch mappings.
