Functions

externIntegrity

Checks the integrity of some extern call.

function externIntegrity(ExternDispatch dispatch, uint256 expectedInputs, uint256 expectedOutputs)
    external
    view
    returns (uint256 actualInputs, uint256 actualOutputs);

Parameters

Name	Type	Description
`dispatch`	`ExternDispatch`	Encoded information about the extern to dispatch. Analogous to the opcode/operand in the interpreter.
`expectedInputs`	`uint256`	The number of inputs expected for the dispatched logic.
`expectedOutputs`	`uint256`	The number of outputs expected for the dispatched logic.

Returns

Name	Type	Description
`actualInputs`	`uint256`	The actual number of inputs for the dispatched logic.
`actualOutputs`	`uint256`	The actual number of outputs for the dispatched logic.

extern

Handles a single dispatch.

function extern(ExternDispatch dispatch, uint256[] calldata inputs)
    external
    view
    returns (uint256[] calldata outputs);

Parameters

Name	Type	Description
`dispatch`	`ExternDispatch`	Encoded information about the extern to dispatch. Analogous to the opcode/operand in the interpreter.
`inputs`	`uint256[]`	The array of inputs for the dispatched logic.

Returns

Name	Type	Description
`outputs`	`uint256[]`	The result of the dispatched logic.
