Struct FieldStore 

pub struct FieldStore {
    pub arg: Expr,
    pub fields: Vec<(usize, Expr)>,
    pub types: Vec<u32>,
}

The parts of an assignment to fields of a row value, as FieldStore.

Fields

arg: Expr

arg: the old row value. A null value is a row whose fields are all null.

fields: Vec<(usize, Expr)>

fieldnums and newvals: the index from 0 of each field that gets a new value, and the new value. In the new value, CaseTest is the old value of the field.

types: Vec<u32>

The type of each field of the row type, for a row that the null value makes.
