Enum prql_compiler::ast::pl::expr::TableExternRef

pub enum TableExternRef {
    LocalTable(String),
    Anchor(String),
}

A reference to a table that is not in scope of this query.

Variants

LocalTable(String)

Actual table in a database, that we can refer to by name in SQL

Anchor(String)

Placeholder for a relation that will be provided later. This is very similar to relational s-strings and may not even be needed for now, so it’s not documented anywhere. But it will be used in the future.

Trait Implementations

impl Clone for TableExternRef

fn clone(&self) -> TableExternRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableExternRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TableExternRef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<TableExternRef> for TableExternRef

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for TableExternRef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
