Methods

impl WasmStack

pub fn try_from_ribosome_encoding(
    maybe_encoded_allocation: RibosomeEncodingBits
) -> Result<WasmStack, RibosomeEncodedValue>

equivalent to TryFrom for WasmStack not implemented as a trait because RibosomeEncodingBits is a primitive and that would couple stacks to ribosome encoding wraps WasmAllocation::try_from_ribosome_encoding internally but has a "higher level" return signature intended for direct use/return in/from ribosome fns

impl WasmStack

pub fn max() -> MemoryBits

pub fn min() -> MemoryInt

pub fn new() -> WasmStack

pub fn next_allocation(
    self,
    length: Length
) -> Result<WasmAllocation, AllocationError>

pub fn allocate(
    &mut self,
    allocation: WasmAllocation
) -> Result<Top, AllocationError>

pub fn deallocate(
    &mut self,
    allocation: WasmAllocation
) -> Result<Top, AllocationError>

pub fn top(self) -> Top

impl WasmStack

pub fn write_string(&mut self, s: &str) -> AllocationResult

Write a string in wasm memory according to stack state.

pub fn write_json<J: TryInto<JsonString>>(
    &mut self,
    jsonable: J
) -> AllocationResult

Write a data struct as a json string in wasm memory according to stack state.
