Struct FromFunction 

pub struct FromFunction {
    pub calls: Vec<(Expr, usize)>,
    pub ordinality: bool,
    pub coldefs: Vec<bool>,
}

A function in FROM, as the functions and funcordinality of a RangeTblEntry of the kind RTE_FUNCTION.

Fields

calls: Vec<(Expr, usize)>

The call of the function, or of each function of ROWS FROM, with the number of columns that it gives. The rows of the calls go side by side, and a call with fewer rows gives nulls.

ordinality: bool

WITH ORDINALITY: the last column is the number of the row, from 1.

coldefs: Vec<bool>

For each call, true when the query gives a column definition list for it, as funccolnames of RangeTblFunction.
