Runtime offsets within a VMComponentContext
for a specific component.
Fields§
§ptr: P

num_lowerings: u32
The number of lowered functions this component will be creating.
num_runtime_memories: u32
The number of memories which are recorded in this component for options.
num_runtime_reallocs: u32
The number of reallocs which are recorded in this component for options.
num_runtime_post_returns: u32
The number of post-returns which are recorded in this component for options.
num_runtime_component_instances: u32
Number of component instances internally in the component (always at least 1).
