Implementations

impl<Data: Send> ImportObjectBuilder<Data>

pub fn new(name: impl AsRef<str>, data: Data) -> WasmEdgeResult<Self>

Creates a new ImportObjectBuilder.

pub fn with_func<Args, Rets>( &mut self, name: impl AsRef<str>, real_func: AsyncFn<'_, '_, '_, '_, Data>, ) -> WasmEdgeResult<&mut Self>

where Args: WasmValTypeList, Rets: WasmValTypeList,
