Struct NetNegative 

pub struct NetNegative(/* private fields */);

A LineChange that removes more than it adds, and the only thing that can be one.

The mark and its evidence are one value, so a row cannot carry a count that says the opposite of the field holding it — and the rule that decides “net-negative” lives here rather than at the site that measures a branch and at every consumer that reads one back. It serializes and reads as the LineChange it holds, so the two counts are what --json carries either way; a document naming a count that is not net-negative is refused where it is read.

Implementations

impl NetNegative

pub fn new(lines: LineChange) -> Option<Self>

The count, when it is one a net-negative branch could have.

pub fn added(&self) -> u64

Lines the branch adds.

pub fn removed(&self) -> u64

Lines it removes, which is more than it adds.
