Enum TableRef 

pub enum TableRef {
    Cte {
        nesting: usize,
        index: usize,
    },
    Derived(TableDerived),
    Table(TableId),
    Arg(ExprArg),
}

Variants

Cte

An aliased table (in a FROM statement or equivalent).

Fields

nesting: usize

What level of nesting the reference is compared to the CTE being referenced.

index: usize

The index of the CTE in the WITH clause

Derived(TableDerived)

A table derived from a query

Table(TableId)

A defined table from the schema

Arg(ExprArg)

The table ref will be provided at a later time (and will become a derived table)

Implementations

impl TableRef

pub fn references(&self, table_id: TableId) -> bool

pub fn is_cte(&self) -> bool

Trait Implementations

impl Clone for TableRef

fn clone(&self) -> TableRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableRef

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

Formats the value using the given formatter.

impl From<ExprArg> for TableRef

fn from(value: ExprArg) -> TableRef

Converts to this type from the input type.

impl From<TableId> for TableRef

fn from(value: TableId) -> TableRef

Converts to this type from the input type.

impl From<TableRef> for Source

fn from(value: TableRef) -> Source

Converts to this type from the input type.

impl PartialEq<TableId> for TableRef

fn eq(&self, other: &TableId) -> 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.

impl PartialEq for TableRef

fn eq(&self, other: &TableRef) -> 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.
