kandi X-RAY | tlv Summary

tlv is a JavaScript library typically used in Database applications. tlv has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Since TLV objects can be constructed, that is be composed as a sequence of child TLV objects, search capabilities by tag are provided. Obviously, these methods only apply to constructed TLVs and do not make sense on primitive ones. These methods are part of the TLV object:.

Your input is the hexadecimal representation of some data. And your expected output is not the Base64 encoding of the UTF-8 data of the hex representation, but rather the data (the bytes) the hex encoding represent, so first decode the bytes e.g. using hex.DecodeString():

Turned out it was hardware-specific problem. Apparently some devices do not support transmitting spoofed LLDP frames for security reasons. Changing adapter to Niantic worked.

Question on invoking another macro_rules in macro_rules definition

Asked 2022-Jan-20 at 21:44

I'm implementing writing TLV packet to somewhat impl std::io::Write.

First I implement WriteBE trait, whose write_be(&mut self, data: T) method can write data with type T to Self. (implementation details omitted)

And I'm trying to use macro_rules! to implement calculation of total packet length in compile time (because most packets have fixed length in my case). macros are as follows:

ANSWER

Answered 2022-Jan-20 at 21:44

Once metavariables inside macro_rules! are captured into some fragment specifier (e.g. expr), they cannot be decomposed anymore. Quoting the reference:

When forwarding a matched fragment to another macro-by-example, matchers in the second macro will see an opaque AST of the fragment type. The second macro can't use literal tokens to match the fragments in the matcher, only a fragment specifier of the same type. The ident, lifetime, and tt fragment types are an exception, and can be matched by literal tokens. The following illustrates this restriction:

QUESTION

Match 190 variables to items in array

Asked 2022-Jan-10 at 18:11

I have a long list of 190 variables, (they are destination routes). And I want to match, if any of these variables, exist in the array arr. (It is necessary for my job to have this many variables).

For some reason, the code below does not work. I'm not sure if it's because I have so many variables to check, perhaps the code is not efficient enough?

The route I'm specifically looking for in the array is "ORY-PSA", which is route72.

The only time my code works/returns true, is if I remove all the || checks, specifically type in the following code:

Answered 2022-Jan-10 at 17:56

At the moment I can't see a better way then doing it the manual way. If it where possible to add the routexxx variables to an array you could make it way more simple.

How to Decode Base64 to TLV in PHP

Asked 2022-Jan-06 at 09:07

I am building an inhouse Invoicing solution for my company. The government requires us to create QR Code fields encoded in Tag-Length-Value (TLV) format.

The TLV encoding shall be as follows:

Tag: the tag value as mentioned above stored in one byte

Length: the length of the byte array resulted from the UTF8 encoding of the field value. The length shall be stored in one byte.

Value: the byte array resulting from the UTF8 encoding of the field value.

In the example they have provided this Base64 Output

Knowing it's binary data, we can echo it with bin2hex(base64_decode($base64)), and see this:

How to create and parse Tag, Length, Value (TLV) in PHP and encode it in Base64

Asked 2021-Dec-05 at 09:20

There is a new regulation from the Government asking all VAT registered companies to implement QR CODE in the new E-Invoice.

The QR code fields shall be encoded in Tag-Length-Value (TLV) format with the tag values specified in the “Tag” column of the adjacent table.
The TLV encoding shall be as follows:
- Tag: the tag value as mentioned above stored in one byte.
- Length: the length of the byte array resulted from the UTF8 encoding of the field value. The length shall be stored in one byte.
- Value: the byte array resulting from the UTF8 encoding of the field value.

How do I create TLV From an Array of Information? Is there a library that I can use?

ANSWER

Answered 2021-Oct-13 at 20:50

Yes, the QR code required is not a normal QR code with a link. It should be TLV base64 encoded. It can be done very easily. the values need to be hexed and then combined which will contain ASCII control characters.

If you still don't get it, Luckily, You can use the following package by Salla to generate a QR code from the array.

Make sure to follow the Tag structure provided by the ZATCA (GAZT previously). The package's example has the correct array:

ANSWER

Answered 2021-Oct-28 at 11:57

If you aren't using the JSON variant, then names aren't used at all in the payload, so yes technically it is perfectly legal to reuse names; however: this might lead to unnecessary problems with existing code - depending on existing code and language / framework specific rules, and could cause confusion. Since that is avoidable, I would advocate using a name like origin_airport_code, or similar.

(The point I'm making here: any code that used the old field probably needs attention; I can see some scenarios where the existing code might still compile after the change, but mean something different, and therefore introduce a bug that would have been avoided if you'd changed the name and forced every usage to be visited)
