Struct NewRow 

pub struct NewRow {
    pub defaults: Map<String, Value>,
    pub carry_forward: Vec<String>,
}

How a new row starts: take defaults, then overwrite each field named in carry_forward with the value the last row that has one carries, so a run of rows sharing a genre or a publisher is typed once.

Fields

defaults: Map<String, Value>

carry_forward: Vec<String>

Implementations

impl NewRow

pub fn new() -> Self
