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.

fn mb_copy_slice( &self, source_handle: Self::ManagedBufferHandle, starting_position: usize, slice_len: usize, dest_handle: Self::ManagedBufferHandle, ) -> Result<(), InvalidSliceError>

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

fn mb_overwrite(&self, handle: Self::ManagedBufferHandle, value: &[u8])

fn mb_set_slice( &self, dest_handle: Self::ManagedBufferHandle, starting_position: usize, source_slice: &[u8], ) -> Result<(), InvalidSliceError>

fn mb_set_random(&self, dest_handle: Self::ManagedBufferHandle, length: usize)

fn mb_append( &self, accumulator_handle: Self::ManagedBufferHandle, data_handle: Self::ManagedBufferHandle, )

fn mb_append_bytes( &self, accumulator_handle: Self::ManagedBufferHandle, bytes: &[u8], )
