Trait to which ext must have to work in processor wasm executor. Currently used only for lazy-pages support.

Required Methods

fn new(context: ProcessorContext) -> Self

Create new

fn into_ext_info<Context>( self, ctx: &mut Context, memory: &impl Memory<Context>, ) -> Result<ExtInfo, MemoryError>

Convert externalities into info.

fn lazy_pages_init_for_program<Context>( ctx: &mut Context, mem: &mut impl Memory<Context>, prog_id: ProgramId, memory_infix: MemoryInfix, stack_end: Option<WasmPage>, globals_config: GlobalsAccessConfig, lazy_pages_costs: LazyPagesCosts, )

Protect and save storage keys for pages which has no data

fn lazy_pages_post_execution_actions<Context>( ctx: &mut Context, mem: &mut impl Memory<Context>, )

Lazy pages program post execution actions

fn lazy_pages_status() -> Status

Returns lazy pages status

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.
