Typesafe API to retrieve enums from strings

[jcready]

You should be able to create these functions yourself (playground):

function isKeyof<T extends {}>(t: T, key: string): key is string & keyof T {
    return key in t;
}

function getEnumValueOrDefault<T extends {}>(e: T, key: string): 0 | T[string & keyof T] {
    return isKeyof(e, key) ? e[key] : 0;
}

Yeah I agree it's possible to workaround, but I was hoping protobuf-ts could include these e.g. in the generated code of each enum so it's right on the type, rather than something we need to pull together or go find.

The enums are just TS enums. No extra properties or methods can be added and have them be TS enums.

Fair enough; well IMO there's room for protobuf-ts to improve the ergonomics of string->enum lookups vs. what TypeScript provides out of the box, but I understand if you disagree.
