Solana edition: Sidri Serialize down to a huge length with a metaplex DIGA2
As a solo developer, you are probably familiar with the joy of using the class’ Std :: Stringin rust, but when you work with blockchain data formats like Anchor and Serpent, things can become a little messy. One usual question is to cope with serialized wires that exceed the maximum length that is allowed for a format.
In this article, we will carry out an example in which we come across a similar problem on the solan with aanchor ‘library’ Serializeby implementation by metaplex D.
Problem: Anchor Serialize a string to a huge length
Suppose our test function looks like this:
rust
Use Anchor_lang :: Prelude ::*;
pub fn test () {{
Let gold = & “gold” .to_string ();
// …
Iche
`
When we try to serialize a string ofgold ‘using the libraryanchor', we get a huge output that does not fit into the expected length. This can lead to a problem trying to use serialized data in our test.
Solution: UsingSerializewith string arguments
To solve this problem, we need to update the functiontest ‘to properly process the arguments of the series. We will make adapted implementation of the Library of the Anchor
, which takes into account the limitations of the length of the series.
`rust
Use Anchor_lang :: Prelude ::*;
Use STD :: FMT;
pub’s anchor structure
Pub data: already
Iche
impl
where
T: Serialize + clone,
{
type exit = (t, already
FN Serialize (Self) -> Self :: Discuss {
Let Mut Buffer = STD :: vec :: vec :: new ();
self.clone (). serialize_to_buffer (& mut interpremor) .unwrap ();
(Self, interpreter)
Iche
Iche
pub fn test () {{
Let gold = string :: from (“gold”);
// …
Iche
`
In this updated code, we create a custom structure of "anchorserrene" that implementing the characteristic of "serialize". We usealready to store serialized data and ensure that it does not exceed the maximum length Metaplex has allowed DOKA2.
Then we update our test function to use a new implementation:
rust
Use Anchor_lang :: Prelude ::*;
pub fn test () {{
Let gold = string :: from (“gold”);
// …
Iche
`
Now, when we start a test, it should produce a serialized output that fits in the expected length.
Conclusion
In this article, we encountered a problem in which a series of entrance toSerializeSerialize
Serialize ‘SerializeImplementation exceeded the maximum length Metaplex allowed DOKA2. By creating a custom implementation of the library and updating our test function accordingly, we were able to solve the problem and ensure that our tests are running without problems.
This example shows how to properly resolve the arguments of the series when using the Anchor Library on Solana, which makes it easier to write slave and effective test cases for your blockchain projects.
