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

Required Associated Constants

const LAZY_PAGES_ENABLED: bool

Whether this extension works with lazy pages.

Required Methods

fn new(context: ProcessorContext) -> Self

Create new

fn lazy_pages_init_for_program( mem: &mut impl Memory, prog_id: ProgramId, stack_end: Option<WasmPage>, globals_config: GlobalsAccessConfig, lazy_pages_weights: LazyPagesWeights )

Protect and save storage keys for pages which has no data

fn lazy_pages_post_execution_actions(mem: &mut impl Memory)

Lazy pages contract post execution actions

fn lazy_pages_status() -> Status

Returns lazy pages status

Implementors

impl ProcessorExternalities for Ext

Empty implementation for non-substrate (and non-lazy-pages) using

const LAZY_PAGES_ENABLED: bool = false
