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", so this trait is not object safe.
