Struct sql::ast::transform::QueryIdentAgg

struct QueryIdentAgg<'a> {
    name: &'a Ident,
    qualifiers: HashMap<Ident, HashSet<Ident>>,
    min_qual_depth: usize,
    fail_on: Option<Ident>,
    err: Option<String>,
}

Visits a Query, assessing catalog item Idents’ use of a specified Ident.

Fields

name: &'a Ident

The name whose usage you want to assess.

qualifiers: HashMap<Ident, HashSet<Ident>>

Tracks all second-level qualifiers used on name in a HashMap, as well as any third-level qualifiers used on those second-level qualifiers in a HashSet.

min_qual_depth: usize

Tracks the least qualified instance of name seen.

fail_on: Option<Ident>

Provides an option to fail the visit if encounters a specified Ident.

err: Option<String>

Implementations

impl<'a> QueryIdentAgg<'a>

fn determine_qual_depth(
    name: &Ident,
    fail_on: Option<Ident>,
    query: &Query<Raw>
) -> Result<usize, String>

Determines the depth of qualification needed to unambiguously reference catalog items in a Query.

Includes an option to fail if a given Ident is encountered.

Results of Ok(usize) indicate that name can be unambiguously referred to with usize parts, e.g. 2 requires schema and item name qualification.

Results of Err indicate that we cannot unambiguously reference name or encountered fail_on, if it’s provided.
