Introduction of Owner Function Solana: Step by Step Guide
The feature of the owner is the basic property of Solana, which allows users to specify who can control and manage their markers. In this article, we will guide this using the owner’s function in the marker account using the Makecount context structural code fragments.
What is the function of the owner?
The function of the Solana owner is used to indicate an entity that has control over the associated markers (such as an account that is or managed by markers). This allows users to authorize certain entities to take action on their name, such as a coin, burn or transfer tokens.
Why implement the owner’s function?
The introduction of the owner’s function brings a number of benefits:
- Allows accurate control of access and permissions
- Allows users to delegate their token management management to reliable units
- Promotes a safe and transparent interaction between the parties
Previous Requirements:
Before immersing the owner’s function, make sure you are:
- Solana Cli mounted on your machine.
- Solana
SDK installed on the computer (optional but recommended).
- Solana block chain and basic knowledge of the basic knowledge of its ecosystem.
Step 1: Define Owner Function
In order to introduce the function of the owner, we need to define it in the context of our tokens account. The function of the owner is a special way that contains information about property entity. Here is an example of a definition:
oxide
Struct TokenContext {
Owner_acount: Accountid,
owner_token_account_id: Accuted,
}
indicate tokenacontcontext {
Fn new
Tokenacountcontext {
Owner_acount: Creator,
owner_token_account_id: token_mint_a,
}
}
Async fn set_owner (
& Mut Self,
Owner_acount: Accountid,
Authority: Authority,
) -> score <(), error> {
// Create a property account and institution
self.owner_account = owner_account;
Self.owner_token_account_id = Authority.0;
OK (())
}
}
In this example, we define the TokenContext Structure, which contains two fields:
- Owner_account
: Identification of Solana for a unit with a marker account.
- Owner_token_account_id
: Identification of Solana, a marker -related entity (eg, invented powers).
Step 2: Introduce Owner Function
Now that we have defined the owner's function, we will introduce our marker account. We will use the TokenacuntContext to administer the property and permit. Here is an example of implementation:
oxide
Structures tokenacount {
Context: TokenacountContext,
}
means tokenacount {
Fn new
Tokenacount {
Context: TokenacountContext :: New (Maker, Token_mint_a),
}
}
ASYNC Fn Set_wner (& Mut Self, Owner_acound: Account, Authority: Authority) -> Result <(), Error> {
// Update property and authorization
Self.context.Set_owner (owner_akounts, authority) .await?;
OK (())
}
}
In this example, we define the Tokenacount structure containing one field:
- Context”: Reference to our example “TokenContext”.
We implement the owner’s function in our marker account by creating a case of “owner_kontext” and configuring it in Token_account. Then we call the Set_owner method to update the property and permission.
Step 3: Use the owner’s function
Now that we have implemented the owner’s function, we use it to manage our marker account.
