pub struct Builder<B: BlockT> { /* private fields */ }

Builder for remote-externalities.

Implementations

impl<B: BlockT> Builder<B>

where B::Hash: DeserializeOwned, B::Header: DeserializeOwned,

pub fn new() -> Self

Create a new builder.

pub fn inject_hashed_key_value( self, injections: Vec<(StorageKey, StorageData)>, ) -> Self

Inject a manual list of key and values to the storage.

pub fn blacklist_hashed_key(self, hashed: &[u8]) -> Self

Configure a state snapshot to be used.

pub fn overwrite_state_version(self, version: StateVersion) -> Self

The state version to use.

pub async fn build(self) -> Result<RemoteExternalities<B>, &'static str>
