Struct Resource

pub struct Resource { /* private fields */ }

The struct holds the necessary cells, headers, and extensions for validating a transaction.

Implementations

impl Resource

pub fn from_mock_tx(mock_tx: &MockTransaction) -> Result<Resource, String>

Create a resource from a mock transaction.

pub fn from_both<L: MockResourceLoader>( mock_tx: &MockTransaction, loader: &mut L, ) -> Result<Resource, String>

Create a resource from both mock transaction and a resource loader.

Trait Implementations

impl CellDataProvider for Resource

fn get_cell_data(&self, out_point: &OutPoint) -> Option<Bytes>

Fetch cell_data from storage

fn get_cell_data_hash(&self, out_point: &OutPoint) -> Option<Byte32>

Fetch cell_data_hash from storage, please note that loading a large amount of cell data and calculating hash may be a performance bottleneck, so here is a separate fn designed to facilitate caching.

fn load_cell_data(&self, cell: &CellMeta) -> Option<Bytes>

Load cell_data from memory, fallback to storage access

fn load_cell_data_hash(&self, cell: &CellMeta) -> Option<Byte32>

Load cell_data_hash from memory, fallback to storage access

impl CellProvider for Resource

fn cell(&self, out_point: &OutPoint, _with_data: bool) -> CellStatus

TODO(doc): @quake

impl Clone for Resource

fn clone(&self) -> Resource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ExtensionProvider for Resource

fn get_block_extension(&self, hash: &Byte32) -> Option<Bytes>

Get the extension field of the given block hash

impl HeaderChecker for Resource

fn check_valid(&self, block_hash: &Byte32) -> Result<(), OutPointError>

Check if header in main chain

impl HeaderProvider for Resource

fn get_header(&self, block_hash: &Byte32) -> Option<HeaderView>

Get the header of the given block hash
