Implementations

impl SourcePlan

pub fn visible_qualifier(&self) -> Option<&str>

SQL-visible relation qualifier for a non-join FROM item. PostgreSQL uses the local function name, not its schema-qualified lookup identity, when a table function has no explicit alias.

pub fn push_expressions<'a>(&'a self, output: &mut Vec<&'a ScalarExpr>)

Append scalar inputs owned by this source, including JOIN predicates; nested query bodies retain their own expression scope.

pub fn collect_tables(&self, output: &mut Vec<(String, Option<String>)>)

impl SourcePlan

pub fn visit_scalar_expressions(&self, visit: &mut dyn FnMut(&ScalarExpr))

Visit every scalar expression this source owns, each root once: join conditions, VALUES rows, function arguments and the expressions of the query bodies nested in derived tables.

Trait Implementations

impl Clone for SourcePlan

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePlan

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SourcePlan

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for SourcePlan

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
