Implementations

impl<N: Network, O: OutputStorage<N>> OutputStore<N, O>

pub fn open(dev: Option<u16>) -> Result<Self>

Initializes the transition output store.

pub fn from(storage: O) -> Self

Initializes a transition output store from storage.

pub fn insert( &self, transition_id: N::TransitionID, outputs: &[Output<N>] ) -> Result<()>

Stores the given (transition ID, output) pair into storage.

pub fn remove(&self, transition_id: &N::TransitionID) -> Result<()>

Removes the output for the given transition ID.

pub fn start_atomic(&self)

Starts an atomic batch write operation.

pub fn is_atomic_in_progress(&self) -> bool

Checks if an atomic batch is in progress.

pub fn atomic_checkpoint(&self)

Checkpoints the atomic batch.

pub fn clear_latest_checkpoint(&self)

Clears the latest atomic batch checkpoint.

pub fn atomic_rewind(&self)

Rewinds the atomic batch to the previous checkpoint.

pub fn abort_atomic(&self)

Aborts an atomic batch write operation.

pub fn finish_atomic(&self) -> Result<()>

impl<N: Network, O: OutputStorage<N>> OutputStore<N, O>

pub fn get_output_ids( &self, transition_id: &N::TransitionID ) -> Result<Vec<Field<N>>>

Returns the output IDs for the given transition ID.

Returns true if the given output ID exists.

pub fn contains_commitment(&self, commitment: &Field<N>) -> Result<bool>

Returns true if the given commitment exists.

pub fn contains_checksum(&self, checksum: &Field<N>) -> bool
