§time_stddev: f64

Standard deviation of processing times

§chunks_processed: usize

Number of chunks processed

§total_time: Duration

Implementations§

Source §

impl NodePerformance

Source

pub fn new(node_id: NodeId) -> Self

Create new performance metrics

Source

pub fn update( &mut self, processing_time: Duration, estimated_cost: f64, success: bool, )
