Available on crate feature component only.

Provides read access to the state commitment tree and related data.

Provided Methods

fn get_sct<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Tree> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Fetch the state commitment tree from nonverifiable storage, preferring the cached tree if it exists.

fn get_anchor_by_height<'life0, 'async_trait>( &'life0 self, height: u64, ) -> Pin<Box<dyn Future<Output = Result<Option<Root>>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Return the SCT root for the given height, if it exists. If the height is not found, return None.

fn spend_info<'life0, 'async_trait>( &'life0 self, nullifier: Nullifier, ) -> Pin<Box<dyn Future<Output = Result<Option<NullificationInfo>>> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Return metadata on the specified nullifier, if it has been spent.

fn pending_nullifiers(&self) -> Vector<Nullifier>

Return the set of nullifiers that have been spent in the current block.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
