Required Methods

fn mb_new_empty(&self) -> Self::ManagedBufferHandle

Requests a new handle from the VM. No longer used extensively.

fn mb_new_from_bytes(&self, bytes: &[u8]) -> Self::ManagedBufferHandle

Requests a new handle from the VM, initialized with some data. No longer used extensively.

fn mb_len(&self, handle: Self::ManagedBufferHandle) -> usize

fn mb_to_boxed_bytes(&self, handle: Self::ManagedBufferHandle) -> BoxedBytes

fn mb_load_slice(
    &self,
    source_handle: Self::ManagedBufferHandle,
    starting_position: usize,
    dest_slice: &mut [u8]
) -> Result<(), InvalidSliceError>

TODO: investigate the impact of using Result<(), ()> on the wasm output.

    &self,
    source_handle: Self::ManagedBufferHandle,
    starting_position: usize,
    slice_len: usize,
