Module safer_ffi::layout

Trait abstractions describing the semantics of “being #[repr(C)]”

Modules

• OpaqueKind
  Type-level enum

Macros

• CType
  Safely implement CType for a #[repr(C)] struct when all its fields are CType.
• ReprC
  Transitioning helper macro: still uses the old ReprC! syntax, but just to forward to the new #[derive_ReprC2($(js)?)] one.
• from_CType_impl_ReprC
  For clarity; this macro may be stabilized if downstream users find it useful *

Structs

• Opaque

Traits

• CType
  Safety (non-exhaustive list at the moment):
• ConcreteReprC
  Alias for ReprC where Self::CLayout::OPAQUE_KIND = OpaqueKind::Concrete
• LegacyCType
  One of the two core traits of this crate (with ReprC).
• ReprC
  The meat of the crate. The trait. This trait describes that a type has a defined / fixed #[repr(C)] layout.

Functions

• from_raw^⚠
• from_raw_unchecked^⚠
• into_raw^⚠

Type Aliases

• CLayoutOf

Attribute Macros

• derive_ReprC
  Safely implement ReprC for a #[repr(C)] struct when all its fields are ReprC.
