function oneOf oneOf<V extends string>(...values: V[]): XmlField<V> A text field limited to known values, such as <parity>none</parity>. Reading throws on a value outside the list, so a firmware that sends something new fails loudly instead of slipping past the type. Examples Read an enumerated value import { assertEquals } from "@std/assert"; import { parse } from "@std/xml"; import { oneOf } from "@hertzg/reolink-api/protocol/xml"; const parity = oneOf("none", "odd", "even"); assertEquals(parity.decode("parity", parse("<p><parity>odd</parity></p>").root), "odd"); Type Parameters V extends string Parameters ...values: V[] The accepted values. Return Type XmlField<V> A field codec for the union of values.
