Function matchExactSchema

Given a Schema, returns a Type Guard that checks that the given value is a object exactly implementing the entries of the Schema.

This Type Guard returns false if a given value contains keys that are not specified in the Schema. If you want to allow unknown keys, see matchSchema

Example

import { matchExactSchema,  match } from 'type-guard-helpers'

const test = {} as unknown
const isFoo = match'foo');
const isBar = match'bar');
const isFooObject = matchExactSchema({
   foo: isFoo,
   bar: isBar
})

if(isFooObject(test)){
   test; // { readonly foo: "foo"; readonly bar: "bar"; }
}
