declare

#[derive(Drop, Serde, Clone)]
enum DeclareResult {
    Success: ContractClass,
    AlreadyDeclared: ContractClass,
}

trait DeclareResultTrait {
    /// Gets inner `ContractClass`
    /// `self` - an instance of the struct `DeclareResult` which is obtained by calling `declare`
    // Returns the `@ContractClass`
    fn contract_class(self: @DeclareResult) -> @ContractClass;
}

fn declare(contract: ByteArray) -> Result<DeclareResult, Array<felt252>>

Declares a contract for later deployment.

Returns the DeclareResult that encapsulated possible outcomes in the enum:

• Success: Contains the successfully declared ContractClass.
• AlreadyDeclared: Contains ContractClass and signals that the contract has already been declared.

See docs of ContractClass for more info about the resulting struct.
