Instance Method Summary
- #clone
- #copy_with(id _id = @id, type _type = @type, offset _offset = @offset)
-
#fetch!(base : Pointer(Void)) : ForeignValue
offset, assuming base points to the start of the struct this field is a member of.
- #id : String
- #offset : UInt64
-
#put!(base : Pointer(Void), value : ForeignValue)
Writes value at base plus this field's offset, assuming base points to the start of the struct this field is a member of.
- #to_s(io)
- #type : ForeignType

def fetch!(base : Pointer(Void)) : ForeignValue
#
offset, assuming base points to the start of the struct this field is a member of.
The latter is not enforced; therefore, this method is considered unsafe.
def put!(base : Pointer(Void), value : ForeignValue)
#
Writes value at base plus this field's offset, assuming base points to the start of the struct this field is a member of.
The latter is not enforced; therefore, this method is considered unsafe.
