Granite Reckoner

一个简单的聚合器，允许在指定的线程数上对 Vec 执行基本统计操作。使用 checked_* 和 partial_cmp 来处理溢出和非比较输入。适用于所有 Rust 内置的数值类型。

用法

use granite_reckoner::Column;

fn main() {
    let container: Vec<u32> = vec![123, 1, 1, 2];
    let column = Column::new();
    let column = column.add_data(container);
    column.print();
    // Default number of threads from constants::NUMBER_OF_NODES
    let _result = column.sum();
    let _result = column.sum_x2(); // sums x^2
    let _result = column.moment_i(); // = average
    let _result = column.moment_ii();
    let _result = column.variance(); // sample variance
    let _result = column.stddev(); // sample standard deviation
    let _result = column.count();
    let _result = column.min();
    let _result = column.max();
    // Specified number of threads within range (1..=constants::NUMBER_OF_NODES)
    let _result = column.sum_t(2);
    let _result = column.sum_x2_t(4);
    let _result = column.moment_i_t(2);
    let _result = column.moment_ii_t(6);
    let _result = column.variance_t(4);
    let _result = column.stddev_t(6);
    let _result = column.count_t(6);
    let _result = column.min_t(4);
    let _result = column.max_t(6);
