Struct wasmedge_sys::instance::memory::MemType

pub struct MemType { /* private fields */ }

Defines the type of a wasm memory instance

Implementations

impl MemType

pub fn create(min: u32, max: Option<u32>, shared: bool) -> WasmEdgeResult<Self>

Create a new MemType to be associated with the given limit range for the capacity.

Arguments

• ‘min’ - The initial size of the linear memory.

• ‘max’ - The upper bound of the linear memory size allowed to grow. If ‘max’ is set ‘None’, then the maximum size will be set u32::MAX.

• shared - Whether the memory is shared or not. Reference Threading proposal for WebAssembly for details about shared memory. If shared is set true, then max MUST not be None.

Errors

If fail to create a MemType, then an error is returned.

Example

let ty = MemType::create(0, Some(u32::MAX), false);

pub fn min(&self) -> u32

Returns the initial size of a Memory.

pub fn max(&self) -> Option<u32>

Returns the maximum size of a Memory allowed to grow.

pub fn shared(&self) -> bool

Returns whether the memory is shared or not.

pub fn as_ptr(&self) -> *const WasmEdge_MemoryTypeContext

Available on crate feature ffi only.

Provides a raw pointer to the inner memory type context.
