Solana problem: serialization string off hug anchoring with Metalapplex Datat2
Ass me a Little Disordered . Accory problem is facing serialized that exceed the maximum toward alloowed by the formats.
In this article, wet-date an example wes wes wes of ‘sirialize ‘sirialize ‘imimplmentation off the Anchor library” sing Metapplex Databox.
The problem: anchor the string in huge to the long
Suppose ur test function is like that:
`Rust
Use Anchor_lang :: Prelude ::*;
Pub Fn Test () {
Let Gold = & "Gold" .to_string ();
// ...
}
Gold 'string we anchor bookshop", we'll jerk that does not-expected long. This can lead toproblems when tesse the serialiid.When we try to serial the
The Solution: usingserializewith string toptics
To solve this problem, we have a test. We’re creet-to-personalization of the "Anchor" anchor bookshop whist take into account the stains of strings length.
`
Rust
Use Anchor_lang :: Prelude ::*;
US STD :: FMT;
Pub Stuct Anchorserene
{
Pub data: VEC
,
}
impl
anocherser per t
Where
T: Serialize + Clone,
{
Type Output = (t, vec
);
FN Serializa (self) -> self :: output {
Let Mut Buffer = STD :: VEC :: VEC :: New ();
self.clone (). Serialize_to_buffer (& Mu Mut Buffer) .unwrap ();
(Self, buffer)
}
}
Pub Fn Test () {
Let god = string :: the extortion ("gold");
// ...
}
In this updded code, we crate a personalized anochersed 'structure that implements the' serialize 'trait. Week avec to store cerialized data and ensurated data it does not does in the maximum lined all Metapplex Datav2.
We're up-to-date dost dose function to dose the new implementation:
Rust
Use Anchor_lang :: Prelude ::*;
Pub Fn Test () {
Let god = string :: the extortion ("gold");
// ...
}
`
Now, whips wes with test, it should produce a serialized output that Adapts to the expected lingthy.
Conclusion
In this article, the welfare athletics intitude in the so- rying inputserious,” By cringing a person-based implementation of the library and uploading ur test accordingly, we have been like the problem and the ensurgity of the ur tests work.
This will be the example manage of the anchors whing the anching library on the “anchor” on Solana, making it will be a robust and efcient tests for the Blockchain Projects.
