Struct sp_wasm_interface::Pointer[][src]

pub struct Pointer<T: PointerType> { /* fields omitted */ }
Expand description

Type to represent a pointer in wasm at the host.

Implementations

Create a new instance of Self.

Calculate the offset from this pointer.

offset is in units of T. So, 3 means 3 * mem::size_of::<T>() as offset to the pointer.

Returns an Option to respect that the pointer could probably overflow.

Create a null pointer.

Cast this pointer of type T to a pointer of type R.
