[−][src]Struct wasmer_vm::LinearMemory
A linear memory instance.
Implementations
impl LinearMemory
[src]
pub fn new(
memory: &MemoryType,
style: &MemoryStyle
) -> Result<Self, MemoryError>
[src]
memory: &MemoryType,
style: &MemoryStyle
) -> Result<Self, MemoryError>
Create a new linear memory instance with specified minimum and maximum number of wasm pages.
This creates a LinearMemory
with owned metadata: this can be used to create a memory
that will be imported into Wasm modules.
pub unsafe fn from_definition(
memory: &MemoryType,
style: &MemoryStyle,
vm_memory_location: NonNull<VMMemoryDefinition>
) -> Result<Self, MemoryError>
[src]
memory: &MemoryType,
style: &MemoryStyle,
vm_memory_location: NonNull<VMMemoryDefinition>
) -> Result<Self, MemoryError>
Create a new linear memory instance with specified minimum and maximum number of wasm pages.
This creates a LinearMemory
with metadata owned by a VM, pointed to by
vm_memory_location
: this can be used to create a local memory.
Safety
vm_memory_location
must point to a valid location in VM memory.
Trait Implementations
impl Debug for LinearMemory
[src]
impl Memory for LinearMemory
[src]
pub fn ty(&self) -> &MemoryType
[src]
Returns the type for this memory.
pub fn style(&self) -> &MemoryStyle
[src]
Returns the memory style for this memory.
pub fn size(&self) -> Pages
[src]
Returns the number of allocated wasm pages.
pub fn grow(&self, delta: Pages) -> Result<Pages, MemoryError>
[src]
Grow memory by the specified amount of wasm pages.
Returns None
if memory can't be grown by the specified amount
of wasm pages.
pub fn vmmemory(&self) -> NonNull<VMMemoryDefinition>
[src]
Return a VMMemoryDefinition
for exposing the memory to compiled wasm code.
impl Send for LinearMemory
[src]
We must implement this because of VMMemoryDefinitionOwnership::VMOwned
.
This is correct because synchronization of memory accesses is controlled
by the VM.
impl Sync for LinearMemory
[src]
This is correct because all internal mutability is protected by a mutex.
