Struct SimpleComplexityAnalyzer

Source

pub struct SimpleComplexityAnalyzer { /* private fields */ }

Expand description

Lightweight complexity analyzer driven by SimpleCostRules.

Implementations§

Source §

impl SimpleComplexityAnalyzer

Source

pub fn new(limit: usize) -> Self

Create with the given cost limit (default field cost = 1).

Source

pub fn with_default_cost(self, cost: usize) -> Self

Override the default cost for fields without an explicit rule.

Source

pub fn add_rule(&mut self, rule: SimpleCostRule)

Register a field rule.

Source

pub fn cost_for_field(&self, name: &str, args: &HashMap<String, usize>) -> usize

Cost for a single field + its args.

Source

pub fn analyze_fields( &self, fields: &[QueryField], ) -> (usize, Vec<(String, usize)>)

Analyse the given list of top-level fields and return total cost + per-field breakdown.

Source

pub fn is_within_limit(&self, fields: &[QueryField]) -> bool

Returns true when query cost is within the limit.
