Struct SelectClause 

pub struct SelectClause { /* private fields */ }

Implementations

impl SelectClause

pub fn variables(&self) -> Vec<Var>

All selected variables. This excludes variables used in assignments

Example

Select ?a (?b as ?c) {
    ...
}

here variables would return just ?a and not ?b or ?c.

pub fn projected_variables(&self) -> Vec<Var>

All selected variables plus all assigned variables. This excludes variables used in assignments

Example

Select ?a (?b as ?c) {
    ...
}

result: [?a, ?c]

pub fn is_star_selection(&self) -> bool

pub fn assignments(&self) -> Vec<Assignment>

All assignments in the select clause.

pub fn select_query(&self) -> Option<SelectQuery>

Trait Implementations

impl AstNode for SelectClause

fn kind() -> SyntaxKind

fn cast(syntax: SyntaxNode) -> Option<Self>

fn syntax(&self) -> &SyntaxNode

fn visible_variables(&self) -> Vec<Var>

Returns all variables “visible” from outside the node.

fn can_cast(kind: SyntaxKind) -> bool

fn has_error(&self) -> bool

fn collect_decendants( &self, matcher: &impl Fn(SyntaxKind) -> bool, ) -> Vec<SyntaxNode>

fn preorder_find_kind(&self, kind: SyntaxKind) -> Vec<SyntaxNode>

fn used_prefixes(&self) -> Vec<String>

fn text(&self) -> String

fn text_until(&self, offset: TextSize) -> String

impl Clone for SelectClause

fn clone(&self) -> SelectClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectClause

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

Formats the value using the given formatter.

impl PartialEq for SelectClause

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