question: does schema.array() validate tuple positions?

[f4rkh4d]

Hey, been using lua-schema in a small config validator and it's been solid. One thing I couldn't figure out: is there a way to validate fixed-position tuples? Like {string, number, boolean} where each position has its own type.

In Zod you'd do z.tuple([z.string(), z.number(), z.boolean()]). Wondering if there's an equivalent or if I should just use a table schema with numeric keys.

Tuples aren't a first-class type yet but you can approximate with a table schema and numeric keys:

local schema = require('schema')

local Point = schema.table({
  [1] = schema.string(),
  [2] = schema.number(),
  [3] = schema.boolean(),
})

It validates but doesn't enforce that the table has exactly 3 elements in strict mode. I've been meaning to add schema.tuple() as sugar for this pattern. Will add it in the next release -- thanks for the concrete use case.
