Traits
Deployable
Simplest trait Deployable
that provides a handy unified mechanism for deployments by implementing a simple receiver for the Deploy message.
All contracts are deployed by sending them a message. While any message can be used for this purpose, best practice is to use the special Deploy message.
This message has a single field, queryId
, provided by the deployer (usually set to zero). If the deployment succeeds, the contract will reply with a DeployOk message and echo the same queryId
in the response.
Source code:
trait Deployable { receive(deploy: Deploy) { self.notify(DeployOk{queryId: deploy.queryId}.toCell()); }}
Usage example:
import "@stdlib/deploy";
contract ExampleContract with Deployable { // Now, this contract has a receiver for Deploy message}
FactoryDeployable
Trait FactoryDeployable
provides a handy unified mechanism for chained deployments.
Source code:
trait FactoryDeployable { receive(deploy: FactoryDeploy) { self.forward(deploy.cashback, DeployOk{queryId: deploy.queryId}.toCell(), false, null); }}
Usage example:
import "@stdlib/deploy";
contract ExampleContract with FactoryDeployable { // Now, this contract has a receiver for FactoryDeploy message}
