§

Dynamic

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.

The actual memory can be resized and moved.

§

Static

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.

Address space is allocated up front.

Implementations§
