Struct QueryComplexityAnalyzer

Source

pub struct QueryComplexityAnalyzer { /* private fields */ }

Expand description

Analyses GraphQL query trees for complexity and depth.

Implementations§

Source §

impl QueryComplexityAnalyzer

Source

pub fn new(config: ComplexityConfig) -> Self

Source

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

Register per-type complexity rules.

Source

pub fn analyze(&self, root: &QueryNode) -> ComplexityResult

Analyse the given query root and return a ComplexityResult.

Source

pub fn node_cost(&self, node: &QueryNode, _depth: usize) -> usize

Returns the cost of node (depth is not used in cost calculation but kept for API compatibility).

Source

pub fn is_allowed(&self, result: &ComplexityResult) -> bool

Returns true if the result is within all configured limits.
