Crate const_field_offset

This crate expose the FieldOffsets derive macro and the types it uses.

The macro allows to get const FieldOffset for member of a #[repr(C)] struct.

The FieldOffset type is re-exported from the field-offset crate.

Structs

• FieldOffset
  Represents a pointer to a field of type U within the type T

Enums

• AllowPin
  Type that can be used in the PinFlag parameter of FieldOffset to specify that this projection is valid on Pin types. See documentation of FieldOffset::new_from_offset_pinned
• NotPinned
  Type that can be used in the PinFlag parameter of FieldOffset to specify that this projection is not valid on Pin types.

Traits

• PinnedDrop
  This trait needs to be implemented if you use the #[pin_drop] attribute. It enables you to implement Drop for your type safely.

Derive Macros

• FieldOffsets
  The macro FieldOffsets adds a FIELD_OFFSETS associated const to the struct. That is an object which has fields with the same name as the fields of the original struct, each field is of type const_field_offset::FieldOffset
