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

Formats the value using the given formatter.

impl Default for StatsCollector

fn default() -> StatsCollector

Returns the “default value” for a type.

impl DocumentVisitor for StatsCollector

type Error = Infallible

Error type returned by visitor methods.

fn visit_scalar( &mut self, _key: &str, _value: &Value, ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called when visiting a scalar value.

fn begin_object( &mut self, _key: &str, ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the start of an object (before visiting children).

fn begin_list( &mut self, _key: &str, _list: &MatrixList, ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the start of a matrix list (before visiting rows).

fn visit_node( &mut self, _node: &Node, _schema: &[String], ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called when visiting a node (row) in a matrix list.

fn begin_document( &mut self, _doc: &Document, _ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the start of document traversal.

Called at the end of document traversal.

fn end_object( &mut self, _key: &str, _ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the end of an object (after visiting children).

fn end_list( &mut self, _key: &str, _list: &MatrixList, _ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the end of a matrix list (after visiting rows).

fn begin_node_children( &mut self, _node: &Node, _ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the start of a node’s children (nested entities).

fn end_node_children( &mut self, _node: &Node, _ctx: &VisitorContext<'_>, ) -> Result<(), Self::Error>

Called at the end of a node’s children.
