Struct QueryLimits 

pub struct QueryLimits {
    pub max_depth: u32,
    pub max_cardinality: usize,
    pub memory_limit_bytes: usize,
    pub timeout_ms: u64,
    pub rate_limit_qps: u32,
    pub circuit_failure_threshold: u32,
    pub circuit_recovery_seconds: u64,
}

Query limits configuration (EPIC-048).

Fields

max_depth: u32

Maximum graph traversal depth (US-002).

max_cardinality: usize

Maximum intermediate cardinality (US-003).

memory_limit_bytes: usize

Memory limit per query in bytes (US-004).

timeout_ms: u64

Query timeout in milliseconds (US-001).

A value of 0 disables the timeout check entirely (no timeout fired). The default is 30_000 (30 seconds). Use 0 only for offline/batch workloads where unbounded execution time is acceptable.

rate_limit_qps: u32

Rate limit: max queries per second per client (US-005).

circuit_failure_threshold: u32

Circuit breaker: failure threshold before tripping (US-006).

circuit_recovery_seconds: u64

Circuit breaker: recovery time in seconds (US-006).
