Struct exonum_testkit::Spec

pub struct Spec<T, Kind> { /* fields omitted */ }

Deploy specification for a Rust artifact. The spec can include zero or more instantiated services.

Examples

#[derive(Debug, ServiceDispatcher, ServiceFactory)]
#[service_factory(artifact_name = "my-service")]
pub struct MyService;
impl Service for MyService {}

impl DefaultInstance for MyService {
    const INSTANCE_ID: InstanceId = 100;
    const INSTANCE_NAME: &'static str = "my-service";
}

let spec = Spec::new(MyService)
    .with_default_instance()
    .with_instance(200, "other-service", 42_u64);
// Deploy `spec` somewhere...

Methods

impl<T, Kind> Spec<T, Kind> where
    T: ServiceFactory, 

pub fn with_instance(
    self,
    id: u32,
    name: impl Into<String>,
    constructor: impl BinaryValue
) -> Spec<T, Kind>

Adds a new built-in service instance to instantiate at the genesis block.

impl<T, Kind> Spec<T, Kind> where
    T: DefaultInstance, 

pub fn with_default_instance(self) -> Spec<T, Kind>

Adds a built-in service instance with the default identifiers to instantiate at the genesis block.

Calling this method several times still results in a single default instance added to the blockchain upon creation.

impl<T> Spec<T, Simple> where
    T: ServiceFactory, 

pub fn new(service: T) -> Spec<T, Simple>

Creates a spec with no support of data migrations.

impl<T> Spec<T, Migrating> where
    T: ServiceFactory, 

pub fn migrating(service: T) -> Spec<T, Migrating>

Creates a spec with support of data migrations.

Trait Implementations

impl<T, Kind> Clone for Spec<T, Kind> where
    T: Clone, 

fn clone(&self) -> Spec<T, Kind>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, Kind> Debug for Spec<T, Kind> where
    Kind: Debug,
    T: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Deploy for Spec<T, Simple> where
    T: ServiceFactory, 

fn deploy(self, genesis: &mut GenesisConfigBuilder, rt: &mut RustRuntimeBuilder)

Modifies the genesis config and Rust runtime builders to deploy self.

impl<T> Deploy for Spec<T, Migrating> where
    T: ServiceFactory + MigrateData, 

fn deploy(self, genesis: &mut GenesisConfigBuilder, rt: &mut RustRuntimeBuilder)

Modifies the genesis config and Rust runtime builders to deploy self.
