CapsuleStore

aztec_rs::embedded_pxe::stores

Struct CapsuleStore 

Source 
pub struct CapsuleStore { /* private fields */ }
Expand description

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.

Source

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

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

Source

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

Store capsule data in a contract-scoped slot.

Source

Load capsule data from a contract-scoped slot.

Source

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

Delete capsule data from a contract-scoped slot.

Source

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.

Source

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.

Source

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.

Source
