Struct lucet_runtime_internals::module::FunctionPointer

pub struct FunctionPointer(_);

FunctionPointer serves entirely as a safer way to work with function pointers than as raw u64 or usize values. It also avoids the need to write them as fn types, which cannot be freely cast from one to another with as. If you need to call a FunctionPointer, use as_usize() and transmute the resulting usize to a fn type with appropriate signature.
