Struct ic_stable_structures::RestrictedMemory
source · pub struct RestrictedMemory<M: Memory> { /* private fields */ }
Expand description
RestrictedMemory creates a limited view of another memory. This allows one to divide the main memory into non-intersecting ranges and use different layouts in each region.

fn size(&self) -> u64
Returns the current size of the stable memory in WebAssembly
pages. (One WebAssembly page is 64Ki bytes.)
source§fn grow(&self, delta: u64) -> i64
fn grow(&self, delta: u64) -> i64
Tries to grow the memory by new_pages many pages containing
zeroes. If successful, returns the previous size of the
memory (in pages). Otherwise, returns -1.
