typescript :如何正确键入由 n 个 N 元组和 m 个 M 元组组成的数组？

Question

//An N-tuple (quadruple?) that is a subset of a row
type Quadruple = [string, string, number, boolean];

//A value that is a subset of a row
type Value = [string];

//A row in the format [...Quadruple[], ...Value[]]
type Row = (string | boolean | number)[]; //this works...but information is lost.

const egRow1: Row = ["id", "name", 1, true, "id2", "name2", 1, true, "id3", "name3", 1, false, "value1", "value2"];
const egRow2: Row = ["id", "name", 1, true, "id2", "name2", 1, true, "value1", "value2"];
const egRow3: Row = ["id", "name", 1, true, "value1", "value2"];

如何有效地输入一行来编码它由 M Quadruples 组成的事实其次是 N Values ?

Answer 1

在我看来，这只能通过枚举 Quadruple 的所有可能数量 (M) 来完成。并联合这些类型:

type Row1 = [string, string, number, boolean, ...Array<string>];
type Row2 = [string, string, number, boolean, string, string, number, boolean, ...Array<string>];
type Row3 = [string, string, number, boolean, string, string, number, boolean, string, string, number, boolean, ...Array<string>];
...
type RowM = [string, string, number, boolean, ..., ...Array<string>];

type Row = Row1 | Row2 | Row3  | ... | RowM;
