Enum wasmer_vm::MemoryStyle

#[repr(u8)]
pub enum MemoryStyle { Dynamic { offset_guard_size: u64, }, Static { bound: Pages, offset_guard_size: u64, }, }
Expand description

Implementation styles for WebAssembly linear memory.

Variants§

§

Dynamic

The actual memory can be resized and moved.

Fields

§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

§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.
