Checking if a given value matches the schema. This is different to parsing because it doesn't return a new value.

import * as v from "valibot";
import { personSchema } from "./schemas";

if (v.is(personSchema, data)) {
  // data is narrowed to Person
}

// const is = Schema.is(schema);
is(data);

v.is(schema, data)

schema.allows(data)

Value.Check(schema, data)

schema.validate(data)

schema.isValidSync(data)
