Struct DropSequence 

pub struct DropSequence<'a> {
    pub drop_span: Span,
    pub sequence_span: Span,
    pub if_exists: Option<Span>,
    pub sequences: Vec<QualifiedName<'a>>,
    pub restrict_or_cascade: Option<CascadeOrRestrict>,
}

Represent a drop sequence statement (PostgreSQL)

let sql = "DROP SEQUENCE myseq CASCADE;";
let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);

let s: DropSequence = match stmts.pop() {
    Some(Statement::DropSequence(s)) => *s,
    _ => panic!("We should get a drop sequence statement")
};

assert!(s.sequences.get(0).unwrap().identifier.as_str() == "myseq");

Fields
