Struct MemoryPageExtent 

pub struct MemoryPageExtent { /* private fields */ }

Wasm and stable memory extents in 64 KiB pages at one instant.

Within one runtime epoch these are monotonic page extents, not allocator liveness or exact live-byte measurements. Consumers that need live bytes must supply an owner-derived bound for allocations within the final page.

pub const fn wasm_pages(self) -> u64

Return the Wasm linear-memory extent in 64 KiB pages.

pub const fn stable_pages(self) -> u64

Return the stable-memory extent in 64 KiB pages.
