Struct FactorsInstanceBuilder

Source

pub struct FactorsInstanceBuilder<'a, F: RuntimeFactors, U> { /* private fields */ }

Expand description

A FactorsInstanceBuilder manages the instantiation of a Spin component instance.

It is generic over the executor’s [RuntimeFactors] and any ad-hoc additional per-instance state needed by the caller.
