Type Alias Mem 

pub type Mem = CopyingMemory;

Compatibility alias for the pre-trait name. Consumers can keep writing Mem; new code should prefer CopyingMemory (when the concrete impl is wanted) or be generic over M: Memory.

Aliased Type

pub struct Mem {
    pub flat_mem: Vec<u8>,
    pub perms: Vec<u8>,
    pub heap_base: u32,
    pub heap_top: u32,
    pub max_heap_pages: u32,
}

Fields

flat_mem: Vec<u8>

Contiguous byte buffer covering 0..flat_mem.len().

perms: Vec<u8>

One permission byte per PAGE_SIZE-page in flat_mem. perms.len() == flat_mem.len() / PAGE_SIZE (rounded up).

heap_base: u32

Heap base address (for sbrk).

heap_top: u32

Current heap top.

max_heap_pages: u32

Maximum heap pages (sbrk refuses beyond this).
