Struct wasmer::vm::VMSharedMemory
source · pub struct VMSharedMemory { /* private fields */ }Expand description
A shared linear memory instance.
Implementations§
sourcepub fn new(
memory: &MemoryType,
style: &MemoryStyle
) -> Result<VMSharedMemory, MemoryError>
pub fn new(
memory: &MemoryType,
style: &MemoryStyle
) -> Result<VMSharedMemory, MemoryError>
Create a new linear memory instance with specified minimum and maximum number of wasm pages.
This creates a Memory with owned metadata: this can be used to create a memory
that will be imported into Wasm modules.
sourcepub unsafe fn from_definition(
memory: &MemoryType,
style: &MemoryStyle,
vm_memory_location: NonNull<VMMemoryDefinition>
) -> Result<VMSharedMemory, MemoryError>
pub unsafe fn from_definition(
memory: &MemoryType,
style: &MemoryStyle,
vm_memory_location: NonNull<VMMemoryDefinition>
) -> Result<VMSharedMemory, MemoryError>
Create a new linear memory instance with specified minimum and maximum number of wasm pages.
This creates a Memory with metadata owned by a VM, pointed to by
vm_memory_location: this can be used to create a local memory.
Safety
vm_memory_locationmust point to a valid location in VM memory.
