enum-values | Library for getting the names and values of typescript enum | SDK library

It should be a simple matter putting all the objects that you want to search through into an array, and then searching in that array.

I can see the error already - "i" is not defined and not assigned. How could you compile this?

Put the enable_if in Foo's template argument list:

There is a enum_primitive crate that exports a macro enum_from_primitive! that automatically derives FromPrimitive which seems to do what you want.

The Admin error code documentation you're referencing only applies to the Node.js SDK today, which is still stuck in the old way of representing API errors. So if you're coding in a language other than Node.js (and using the latest available Firebase SDKs), disregard those legacy error codes and just handle the ones that are explicitly defined in the provided enums. There's no direct 1:1 mapping between those legacy and new error codes in many cases.

For most up-to-date information regarding error codes you should refer to Admin SDK error handling.

The old mismatched-credential error code used to represent two separate error conditions:

1. Actual token mismatch errors where the caller is not authorized to send to the given device token.
2. Other general permission errors due to the authorization credential lacking the required IAM roles/permissions.

The new v7 Java SDK differentiates between these two cases. Case 1 is represented by MessagingErrorCode.SENDER_ID_MISMATCH.

SENDER_ID_MISMATCH The authenticated sender ID is different from the sender ID for the registration token. This usually means the sender and the target registration token are not in the same Firebase project.

Case 2 results in an ErrorCode.PERMISSION_DENIED with no MessagingErrorCode value.

PERMISSION_DENIED Client does not have sufficient permission. This can happen because the OAuth token does not have the right scopes, the client does not have permission, or the API has not been enabled for the client project.

Most developers would only want to handle case 1 in their code. Case 2 is almost always a configuration error.

This is how enum works in typescript. It creates an object which will map the string keys to numbers and numbers back to those keys (Documentation)

Reverse mappings

In addition to creating an object with property names for members, numeric enums members also get a reverse mapping from enum values to enum names.

This how the enum is transpiled to javascript (Typescript playground)

You can create an extension method in a static class.

I found the solution

object . foo in C means (approximately) "add an offset (associated with foo) to (char*)&object cast the result to a pointer to the type associated with foo and then dereference".

Unlike in object-oriented programming languages, C's ./-> is not an operator for accessing things somehow associated with an object.

If you don't want to be adding offsets to addresses of lvalues, you should be grouping things together differently, e.g., via a common prefix:
