error: implicit autoref creates a reference to the dereference of a raw pointer

     |                  |
     |                  this raw pointer has type `*mut yaml_parser_t`
     |
     = note: creating a reference requires the pointer target to be valid and imposes aliasing requirements
     = note: references are created through calls to explicit `Deref(Mut)::deref(_mut)` implementations
     = note: `#[deny(dangerous_implicit_autorefs)]` on by default
  help: try using a raw pointer method instead; or if this reference is intentional, make it explicit
