System API for the sandbox.

Required Associated Types

type T: Config

The runtime system config.

Required Methods

fn build_block(&mut self) -> BlockNumberFor<Self::T>

Build a new empty block and return the new height.

fn build_blocks(&mut self, n: u32) -> BlockNumberFor<Self::T>

Build n empty blocks and return the new height.

Arguments

• n - The number of blocks to build.

fn block_number(&mut self) -> BlockNumberFor<Self::T>

Return the current height of the chain.

fn events(&mut self) -> Vec<EventRecordOf<Self::T>>

Return the events of the current block so far.

fn reset_events(&mut self)

Reset the events of the current block.

fn runtime_call<Origin: Into<<RuntimeCall<Self::T> as Dispatchable>::RuntimeOrigin>>( &mut self, call: RuntimeCall<Self::T>, origin: Origin, ) -> DispatchResultWithInfo<<RuntimeCall<Self::T> as Dispatchable>::PostInfo>

Execute a runtime call (dispatchable).

Arguments

• call - The runtime call to execute.
• origin - The origin of the call.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
