Implementations

impl Context

pub fn deploy_contract(&mut self, data: Bytes) -> OutPoint

👎 Deprecated since 0.1.1:

Please use the deploy_cell function instead

pub fn deploy_cell(&mut self, data: Bytes) -> OutPoint

Deploy a cell return the out-point of the cell

pub fn get_contract_out_point(&self, data_hash: &Byte32) -> Option<OutPoint>

👎 Deprecated since 0.1.1:

Please use the get_cell_by_data_hash function instead

pub fn get_cell_by_data_hash(&self, data_hash: &Byte32) -> Option<OutPoint>

Get the out-point of a cell by data_hash the cell must has deployed to this context

pub fn create_cell(&mut self, cell: CellOutput, data: Bytes) -> OutPoint

Create a cell with data return the out-point

pub fn create_cell_with_out_point(
    &mut self,
    out_point: OutPoint,
    cell: CellOutput,
    data: Bytes
)

Create cell with specified out-point and cell data

pub fn insert_cell(
    &mut self,
    out_point: OutPoint,
    cell: CellOutput,
    data: Bytes
)

👎 Deprecated since 0.1.1:

Please use the create_cell_with_out_point function instead

pub fn get_cell(&self, out_point: &OutPoint) -> Option<(CellOutput, Bytes)>

Get cell output and data by out-point

pub fn build_script(
    &mut self,
    out_point: &OutPoint,
    args: Bytes
) -> Option<Script>

Build script with out_point and args return none if the out-point is not exist

pub fn complete_tx(&mut self, tx: TransactionView) -> TransactionView

Complete cell deps for a transaction this function searches context cells; generate cell dep for referenced scripts.

pub fn capture_debug(&self) -> bool

pub fn set_capture_debug(&mut self, capture_debug: bool)

Capture debug output, default value is false

pub fn captured_messages(&self) -> Vec<Message>

return captured messages

pub fn verify_tx(
    &self,
    tx: &TransactionView,
    max_cycles: u64
) -> Result<Cycle, CKBError>

Verify the transaction in CKB-VM
