Enum CPointer 

pub enum CPointer {
    Text,
    Memory,
    Handle,
    Out,
    Struct,
}

What a C pointer type crosses as

Variants

Text

char *, const unsigned char *: a warp text (a parameter its NUL-terminated letters in linear memory)

Memory

void *, int *: a parameter points into linear memory; a result is a handle

Handle

sqlite3 *, FILE *: an id into the run’s handle table (CHandles), 0 is NULL

Out

sqlite3 **ppDb: left out of the warp call; the first one becomes the result unless a struct output is, the others receive NULL

Struct

wasmtime_instance_t *instance as the call’s output: the struct read back as a map (c_structs.rs)
