Method data_size

crates/wasmtime/src/runtime/memory.rs:506–508

Returns the byte length of this memory. WebAssembly memories are made up of a whole number of pages, so the byte size returned will always be a multiple of this memory's page size. Note that different Wasm memories may have different page sizes. You can get a memory's page size via the [`Memory::page_size`] method. By default the page size is 64KiB (aka `0x10000`, `2**16`, `1<<16`, or `65536`) b
