Required Methods

fn try_to_enable_lazy_pages(prefix: [u8; 32]) -> bool

Try to enable and initialize lazy pages env

fn init_for_program<Context>( ctx: &mut Context, mem: &mut impl Memory<Context>, program_id: ProgramId, memory_infix: MemoryInfix, stack_end: Option<WasmPage>, globals_config: GlobalsAccessConfig, costs: LazyPagesCosts, )

Protect and save storage keys for pages which has no data

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

Remove lazy-pages protection, returns wasm memory begin addr

fn update_lazy_pages_and_protect_again<Context>( ctx: &mut Context, mem: &mut impl Memory<Context>, old_mem_addr: Option<HostPointer>, old_mem_size: WasmPagesAmount, new_mem_addr: HostPointer, )

Protect lazy-pages and set new wasm mem addr and size, if they have been changed.

fn get_write_accessed_pages() -> Vec<GearPage>

Returns list of released pages numbers.

fn get_status() -> Status

Returns lazy pages actual status.

fn pre_process_memory_accesses( reads: &[MemoryInterval], writes: &[MemoryInterval], gas_counter: &mut u64, ) -> Result<(), ProcessAccessError>

Pre-process memory access in syscalls in lazy-pages.

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.
