Struct TypeChange 

pub struct TypeChange {
    pub name: Option<QualifiedName>,
    pub ty: Option<LogicalType>,
    pub uses: Vec<QualifiedName>,
    pub if_not_exists: bool,
    pub or_replace: bool,
    pub cascade: bool,
}

A bound CREATE TYPE or DROP TYPE.

Fields

name: Option<QualifiedName>

The full name. None for a DROP TYPE IF EXISTS of one that is not there.

ty: Option<LogicalType>

What a create makes the name stand for, and None on a drop.

uses: Vec<QualifiedName>

The made types a create read its type through, which it will depend on.

if_not_exists: bool

Whether a create over a type that is there does nothing.

or_replace: bool

Whether a create replaces a type that is there.

cascade: bool

Whether a drop takes the types made from this one with it.
