Module libffi::low

source · [−]

Expand description

A low-level wrapping of libffi, this layer makes no attempts at safety, but tries to provide a somewhat more idiomatic interface.

This module also re-exports types and constants necessary for using the library, so it should not be generally necessary to use the raw module. While this is a bit “Rustier” than raw, I’ve avoided drastic renaming in favor of hewing close to the libffi API. See middle for an easier-to-use approach.
