Implement Metadata borsh deserialization

[gabrielkoerich]

Hi guys!

This PR creates 3 accounts:

• Metadata
• MetadataData
• Creator

It uses the same schema Metaplex uses to deserialize objects from the buffer array.

I also created a test to show how it works, but basically would be something like this:

use Tighten\SolanaPhpSdk\Accounts\Metadata;

$metadata = Metadata::fromBuffer($this->getBuffer());

dump($metadata);
Tighten\SolanaPhpSdk\Accounts\Metadata^ {#460
  +"key": 4
  +"updateAuthority": "AmivaqHeZBgUZkzEZ44Mi9zQJruExZMP4PVRYduFVkaS"
  +"mint": "FeGDLocrdh5AVH5EMFsAx583hF6f7bqEaVnCE5UEzizg"
  +"data": Tighten\SolanaPhpSdk\Accounts\MetadataData^ {#1385
    +"name": "ROGUE SHARKS #2967"
    +"symbol": "SHARK"
    +"uri": "https://arweave.net/UkM-RbNKE7FARRIozpQ1JLXa5qNvQW7wxrAKtailx5M"
    +"sellerFeeBasisPoints": 420
    +"creators": array:2 [
      0 => Tighten\SolanaPhpSdk\Accounts\Creator^ {#409
        +"address": "HfQgpZzi7Ka241nfCqwoU6A6br8NBjUsdfW2GZ11gHSN"
        +"verified": 1
        +"share": 0
      }
      1 => Tighten\SolanaPhpSdk\Accounts\Creator^ {#986
        +"address": "AmivaqHeZBgUZkzEZ44Mi9zQJruExZMP4PVRYduFVkaS"
        +"verified": 1
        +"share": 100
      }
    ]
  }
  +"primarySaleHappened": 1
  +"isMutable": 1
}

So we finally can deserialize them on PHP! 🚀

This looks great to me, and thank you for your hard work! But I'm also not super experienced with how this should look.

@exzachlyvv do you have time to review?

[exzachlyvv]

Looks solid to me, I say go for it :D

Glad to see the Borsh serialize and deserialize are working for you. It has unit tests with it for the basics but is not very well battle-tested.

Thank you @gabrielkoerich, I got stuck with implementing it, but this looks solid. Will give it a spin in a project I'm working on right now.

Hey @gabrielkoerich tested it on my pet project and it works like a charm. Thank you so much.

Example I used:

$buffer = Tighten\SolanaPhpSdk\Util\Buffer::from(base64_decode("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"));

$metadata = Tighten\SolanaPhpSdk\Accounts\Metadata::fromBuffer($buffer->toArray());

Results in:

@neverything awesome to see it helped!

@exzachlyvv yeah, this wouldn't be possible without your work, thanks!

[mattstauffer]

Fantastic--thanks so much for your work @gabrielkoerich! Tagging now.
