[−][src]Struct lucet_module::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.
