Source
pub fn assemble_vc_key_package_upload<Storage: StorageProvider>(
    storage: &Storage,
    epoch_id: EpochId,
    generation: u32,
    key_package_info: Vec<KeyPackageInfo>,
) -> Result<KeyPackageUpload, VirtualClientsError>
Available on crate feature extensions-draft and crate feature virtual-clients-draft and (32-bit or 64-bit) only.
Expand description

Build a KeyPackageUpload for epoch_id from a batch’s generation and its KeyPackageInfo entries, filling leaf_index from the EmulationEpochState stored for that epoch.

The virtual client calls this after building a batch of KeyPackages with KeyPackageBuilder::build_vc_batch to assemble the message it hands to its sibling. generation is the single key_package operation generation the batch consumed.

Returns VirtualClientsError::MissingEmulationEpochState if no state is registered for epoch_id.
