Struct CapsuleStore 

pub struct CapsuleStore { /* private fields */ }

Stores ephemeral capsule data that is consumed during execution.

Capsules are private data blobs passed to contract functions via oracle calls. They are consumed (deleted) after being read.

Implementations

impl CapsuleStore

pub fn new(kv: Arc<dyn KvStore>) -> Self

pub async fn add(&self, contract: &Fr, capsule: &[Vec<Fr>]) -> Result<(), Error>

Store a capsule (a list of field element arrays).

pub async fn pop(&self, contract: &Fr) -> Result<Option<Vec<Vec<Fr>>>, Error>

Pop a capsule for the given contract (consumes it).

pub async fn store_capsule( &self, contract_address: &AztecAddress, slot: &Fr, capsule: &[Fr], ) -> Result<(), Error>

Store capsule data in a contract-scoped slot.

pub async fn load_capsule( &self, contract_address: &AztecAddress, slot: &Fr, ) -> Result<Option<Vec<Fr>>, Error>

Load capsule data from a contract-scoped slot.

pub async fn delete_capsule( &self, contract_address: &AztecAddress, slot: &Fr, ) -> Result<(), Error>

Delete capsule data from a contract-scoped slot.

pub async fn copy_capsule( &self, contract_address: &AztecAddress, src_slot: &Fr, dst_slot: &Fr, num_entries: usize, ) -> Result<(), Error>

Copy a contiguous region of contract-scoped slots.

pub async fn append_to_capsule_array( &self, contract_address: &AztecAddress, base_slot: &Fr, content: &[Vec<Fr>], ) -> Result<(), Error>

Append entries to a capsule array stored at base_slot.

pub async fn read_capsule_array( &self, contract_address: &AztecAddress, base_slot: &Fr, ) -> Result<Vec<Vec<Fr>>, Error>

Read all entries from a capsule array stored at base_slot.

pub async fn set_capsule_array( &self, contract_address: &AztecAddress, base_slot: &Fr, content: &[Vec<Fr>], ) -> Result<(), Error>

Replace the entire capsule array stored at base_slot.
