Struct ResourceLimits 

#[non_exhaustive]
pub struct ResourceLimits {
    pub max_concurrent_nodes: usize,
    pub max_execution_records: usize,
    pub max_checkpoint_bytes: usize,
    pub max_dag_nodes: usize,
    pub max_sequential_steps: usize,
}

Configurable resource boundaries for graph execution.

Provides hard limits on concurrency, memory usage, and cardinality to prevent unbounded resource consumption in production.

Defaults

All defaults are generous enough for typical workloads:

• 64 concurrent DAG nodes
• 10,000 execution history records
• 10 MB max checkpoint payload
• 10,000 max DAG nodes
• 1,000 max sequential steps (loop protection)

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_concurrent_nodes: usize

Maximum concurrent nodes in a DAG wave (default: 64).

max_execution_records: usize

Maximum execution history records retained in memory (default: 10,000).

max_checkpoint_bytes: usize

Maximum checkpoint payload size in bytes (default: 10 MB).

max_dag_nodes: usize

Maximum DAG nodes allowed (default: 10,000).

max_sequential_steps: usize

Maximum sequential steps before aborting (default: 1,000). Prevents infinite loops when conditional edges create cycles.

Implementations

impl ResourceLimits

pub fn with_max_concurrent_nodes(self, n: usize) -> Self
