Struct Declared 

pub struct Declared { /* private fields */ }

A declaration as somebody wrote it, before a catalog turned the names into column indexes.

Clustering holds indexes, which means it cannot be built without the table in hand, and the text is typed in a session that may name a table this database does not have. So the parse produces this and whoever has the catalog turns it into the real thing, which is also where the name errors come from and where they can say which table they are about.

Implementations

impl Declared

pub fn table(&self) -> &str

The table the declaration is about, as it was written.

pub fn width(&self) -> Option<Width>

The width the text named, or None when it named none and the column’s type decides.

pub fn columns(&self) -> &[String]

The columns, outermost first, as they were written.
