Enum wasmer_vm::MemoryStyle

pub enum MemoryStyle {
    Dynamic {
        offset_guard_size: u64,
    },
    Static {
        bound: Pages,
        offset_guard_size: u64,
    },
}

Implementation styles for WebAssembly linear memory.

Variants

Dynamic

The actual memory can be resized and moved.

Fields of Dynamic

offset_guard_size: u64

Our chosen offset-guard size.

It represents the size in bytes of extra guard pages after the end to optimize loads and stores with constant offsets.

Static

Address space is allocated up front.

Fields of Static

bound: Pages

The number of mapped and unmapped pages.

offset_guard_size: u64

Our chosen offset-guard size.

It represents the size in bytes of extra guard pages after the end to optimize loads and stores with constant offsets.
