Solana: Unable to use external crates (eg, eagle_solana_vrf) on the Solana playground **
As a developer who works with Solan Blockchain, you are probably familiar with the ease of using external crates and libraries for testing and building smart contracts. However, when it comes to an environment of a playground in Solana, there is a problem that can do things more challenging than expected.
In this article, we will enter into why you could encounter problems when trying to use external crates like Orrao_Solana_vrf on the Solana playground.
** What are the outer crates?
Exterior crates are packets written in programming languages ​​other than Rust (Solan’s mother tongue) that provide functionality useful for building smart contracts. Examples include libraries for testing, error removal and interaction with external data sources.
Problem: Orao_Solana_vrf
One of the most common outdoor crates you could encounter in Solana is eagle_solana_vrf '. This crate provides a set of service programs to check and check the transaction at Solan Blockchain. However, when you try to use it in the surroundings of a playground in Solana, you may have problems like:
* Compilation errors : The addiction of the crate may not be compatible with the other translator using the Solana playground.
* Errors in Runtime
: The crate may not provide the expected functionality or messages about the performance duration.
unsuccessful tests : tests written using an external crate can succeed because of problems with the crate itself.
Solutions and bypasses
To overcome the thesis challenges, try the following solutions:
- Update your addiction : Be sure to launch the latest version ofOrao_Solana_vrf
to ensure compatibility with the Solan Solan Playground.
- Use a different crate : If possible, try using another outer crate that is compatible with the other translator using the Solana playground.
- Carefully test your code : thoroughly test your smart contract and its addiction before arranging it in Solana Blockchain.
- Come to the Community : Post up your issue on the Discord Solan Channel or the official salt of Solan Subreddit, where you can request the help of experienced developers.
Conclusion
Although the use of external crates in the surrounding playground in Solana may be a little more challenging than expected, solutions are available to overcome the thesis problems. By updating addictions, tripping of different crates, with careful testing and reach of the community, you should be able to solve any problems associated withOrao_Solana_vrf`.
