Enum ScopeType 

pub enum ScopeType {
    Root,
    Subquery,
    DerivedTable,
    Cte,
    Union,
    Udtf,
}

The kind of scope a query fragment lives in.

Variants

Root

The outermost query.

Subquery

A scalar or lateral subquery in a WHERE / SELECT / HAVING expression.

DerivedTable

A derived table (subquery in FROM).

Cte

A CTE definition (WITH name AS (...)).

Union

One branch of a UNION / INTERSECT / EXCEPT.

Udtf

A user-defined table function (UDTF) / LATERAL.

Trait Implementations

impl Clone for ScopeType

fn clone(&self) -> ScopeType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScopeType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ScopeType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScopeType

fn eq(&self, other: &ScopeType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
