Module ffi

Platform-specific types, as defined by C.

Code that interacts via FFI will almost certainly be using the base types provided by C, which aren’t nearly as nicely defined as Rust’s primitive types. This module provides types which will match those defined by C, so that code that interacts with C will refer to the correct types.

Modules

• c_strExperimental
  CStr and its related types.
• va_listExperimental
  C’s “variable arguments”

Structs

• CStr
  Representation of a borrowed C string.
• FromBytesUntilNulError
  An error indicating that no nul byte was present.
• FromBytesWithNulError
  An error indicating that a nul byte was not in the expected position.
• VaListExperimental
  A wrapper for a va_list
• VaListImplExperimental
  x86_64 ABI implementation of a va_list.

• c_void
  Equivalent to C’s void type when used as a pointer.
