Expand description
Tunable parameters for WebAssembly compilation.
This is the reference implementation of the Tunables
trait,
used by default.
You can use this as a template for creating a custom Tunables implementation or use composition to wrap your Tunables around this one. The later approach is demonstrated in the tunables-limit-memory example.
Fields§
§static_memory_bound: Pages
For static heaps, the size in wasm pages of the heap protected by bounds checking.
static_memory_offset_guard_size: u64
The size in bytes of the offset guard for static heaps.
dynamic_memory_offset_guard_size: u64
The size in bytes of the offset guard for dynamic heaps.
