arch:: wasm32:: memory_size
pub fn memory_size(mem: u32) -> usize
Corresponding intrinsic to wasm's
This function, when called, will return the current memory size in units of pages. The current WebAssembly page size is 65536 bytes (64 KB).
mem is the numerical index of which memory to return the
size of. Note that currently the WebAssembly specification only supports one
memory, so it is required that zero is passed in. The argument is present to
be forward-compatible with future WebAssembly revisions. If a nonzero
argument is passed to this function it will currently unconditionally abort.
