rsdv (version 0.2.0)

metadata_from_json: Deserialize metadata from a JSON string

Description

Deserialize metadata from a JSON string

Usage

metadata_from_json(json)

Value

An rsdv_metadata object. Constraints are reconstructed with their original S3 classes so check_constraint() dispatches correctly.

Arguments

json

A JSON character string produced by metadata_to_json().

Examples

meta <- metadata() |>
  set_column_type("a", "numerical") |>
  set_column_type("b", "numerical") |>
  add_constraint(inequality_constraint("a", "b", type = "lt"))
metadata_from_json(metadata_to_json(meta))
