从单位获取持续时间

Question

假设我知道一个单位和这个单位的数量。有没有办法从中获取 Duration 对象？

类似于Duration.fromUnitAmount(unit: DurationUnit, amount: number): Duration 或DurationUnit.getDuration(amount: number): Duration，或从{ unit: myUnit, amount: myAmount } 等对象构建Duration 对象。

我已经为它创建了一个函数，但我想知道是否为此内置了一些东西。这是函数：

    static getDurationFromAmountOfUnit(unit: DurationUnit, amount: number) {
        switch (unit) {
            case 'years':
            case 'year':
                return Duration.fromObject({year: amount});
            case 'quarters':
            case 'quarter':
                return Duration.fromObject({quarter: amount});
            case 'months':
            case 'month':
                return Duration.fromObject({month: amount});
            case 'weeks':
            case 'week':
                return Duration.fromObject({week: amount});
            case 'days':
            case 'day':
                return Duration.fromObject({day: amount});
            case 'hours':
            case 'hour':
                return Duration.fromObject({hour: amount});
            case 'minutes':
            case 'minute':
                return Duration.fromObject({minute: amount});
            case 'seconds':
            case 'second':
                return Duration.fromObject({second: amount});
            case 'milliseconds':
            case 'millisecond':
                return Duration.fromObject({millisecond: amount});
        }
    }

这有帮助吗：

import { Duration, DurationUnit } from 'luxon';

function getDuration(unit: DurationUnit, amount: number) {
  return Duration.fromObject({
    [unit]: amount,
  });
}
