Struct N1QueryTracker 

pub struct N1QueryTracker { /* private fields */ }

Tracks lazy load queries for N+1 detection.

Implementations

impl N1QueryTracker

pub fn new() -> Self

Create a new tracker with default threshold (3).

pub fn with_threshold(self, threshold: usize) -> Self

Set the threshold for N+1 warnings.

A warning is emitted when the number of lazy loads for a single relationship reaches this threshold.

pub fn threshold(&self) -> usize

Get the current threshold.

pub fn is_enabled(&self) -> bool

Check if detection is enabled.

pub fn disable(&mut self)

Disable N+1 detection.

pub fn enable(&mut self)

Enable N+1 detection.

pub fn record_load( &mut self, parent_type: &'static str, relationship: &'static str, )

Record a lazy load query.

This should be called whenever a lazy relationship is loaded. When the count for a (parent_type, relationship) pair reaches the threshold, a warning is emitted.

pub fn reset(&mut self)

Reset all counts and call sites.

Call this at the start of a new request or transaction scope.

pub fn count_for( &self, parent_type: &'static str, relationship: &'static str, ) -> usize

Get the current count for a specific relationship.

pub fn stats(&self) -> N1Stats

Get statistics about N+1 detection.

pub fn call_sites(&self) -> &[CallSite]

Get all call sites (for debugging).

Trait Implementations

impl Debug for N1QueryTracker

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

impl Default for N1QueryTracker

fn default() -> Self

Returns the “default value” for a type.
