Struct ProfilingNode 

pub struct ProfilingNode { /* private fields */ }

An owned node of the query-profiling tree: the metrics recorded at this node (name → value, both strings) plus its child nodes, in DuckDB’s order.

Materialised from duckdb_get_profiling_info, so it stays valid after further queries and after the connection is dropped.

Implementations

impl ProfilingNode

pub fn metrics(&self) -> &HashMap<String, String>

All metrics recorded at this node (metric name → value string).

pub fn metric(&self, key: &str) -> Option<&str>

The value of a single metric at this node, if present.

pub fn children(&self) -> &[ProfilingNode]

This node’s child nodes, in DuckDB’s order.

Trait Implementations

impl Clone for ProfilingNode

fn clone(&self) -> ProfilingNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProfilingNode

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

Formats the value using the given formatter.

impl Default for ProfilingNode

fn default() -> ProfilingNode

Returns the “default value” for a type.

impl Eq for ProfilingNode

impl PartialEq for ProfilingNode

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