Enum Query 

pub enum Query<N: Network, B: BlockStorage<N>> {
    VM(BlockStore<N, B>),
    REST(RestQuery<N>),
    STATIC(StaticQuery<N>),
}

Allows inspecting the state of the blockstain using either local state or a remote endpoint.

Variants

VM(BlockStore<N, B>)

REST(RestQuery<N>)

Query state using a node’s REST API.

STATIC(StaticQuery<N>)

Implementations

fn clone(&self) -> Query<N, B>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N: Network, B: BlockStorage<N>> From<&BlockStore<N, B>> for Query<N, B>

Initialize the Query object from a local BlockStore.

fn from(block_store: &BlockStore<N, B>) -> Self

Converts to this type from the input type.

impl<N: Network, B: BlockStorage<N>> From<BlockStore<N, B>> for Query<N, B>
