Function tuple

Decoder for tuples with fixed length and types.

Example

const pointDecoder = JsonDecoder.tuple(
  [JsonDecoder.number, JsonDecoder.number],
  'Point'
);

pointDecoder.decode([1, 2]); // Ok<[number, number]>
pointDecoder.decode([1, 2, 3]); // Err({error: '<Point> tuple decoder failed because it received a tuple of length 3 but expected 2'})

tuple<T extends readonly [] | readonly Decoder<any>[]>(
decoders: T,
decoderName: string,
): Decoder<TupleOfResults<T>>
Type Parameters
- T extends readonly [] | readonly Decoder<any>[]
Parameters
- decoders: T
  Array of decoders for each tuple element
- decoderName: string
  How to display the name of the object being decoded in errors
Returns Decoder<TupleOfResults<T>>
A decoder that validates and returns tuples
