Struct deltalake::datafusion::logical_expr::logical_plan::display::IndentVisitor
source · pub struct IndentVisitor<'a, 'b> { /* private fields */ }
Expand description
Formats plans with a single line per node. For example:
Projection: id
Filter: state Eq Utf8("CO")
CsvScan: employee.csv projection=Some([0, 3])“;
Implementations§
source§impl<'a, 'b> IndentVisitor<'a, 'b>
impl<'a, 'b> IndentVisitor<'a, 'b>
sourcepub fn new(f: &'a mut Formatter<'b>, with_schema: bool) -> IndentVisitor<'a, 'b>
pub fn new(f: &'a mut Formatter<'b>, with_schema: bool) -> IndentVisitor<'a, 'b>
Create a visitor that will write a formatted LogicalPlan to f. If with_schema
is
true, includes schema information on each line.

§type Node = LogicalPlan
type Node = LogicalPlan
The node type which is visitable.
source§fn f_down(
&mut self,
plan: &LogicalPlan
) -> Result<TreeNodeRecursion, DataFusionError>
fn f_down( &mut self, plan: &LogicalPlan ) -> Result<TreeNodeRecursion, DataFusionError>
Invoked before any children of
node
are visited.
Default implementation simply continues the recursion.source§fn f_up(
&mut self,
_plan: &LogicalPlan
) -> Result<TreeNodeRecursion, DataFusionError>
fn f_up( &mut self, _plan: &LogicalPlan ) -> Result<TreeNodeRecursion, DataFusionError>
Invoked after all children of
node
are visited.
Default implementation simply continues the recursion.Auto Trait Implementations§
