Module deno_libffi::low [−][src]
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.
