OrleanSpaces.Analyzers

NuGet v0.1.1

Features

  • OSA001 - Avoid instantiation of empty SpaceTuple by default constructor or expression.
  • OSA002 - Avoid constructor instantiation of SpaceTemplate having only SpaceUnit type arguments.
  • OSA003 - The supplied argument type is not supported.

OrleanSpaces

NuGet v0.2.0

Features

  • Avoiding generation of async state machines via async eliding on some of the methods of ISpaceAgent.

Breaking Changes

  • SpaceUnit.Null has been removed.

The idea of this property was to serve a static value of type SpaceUnit via a read-only reference, as opposed to new'ing the same value every time. The problem was that in actuality it is more performant to simply new a value as opposed to serving a reference to a pre-initialized value. The reason is that the size of the struct is 1, and when we return via ref, it's returning a reference to the static value (so an IntPtr) which is of size 4 (x86 processor architecture), and size 8 (x64 processor architecture). So its makes much more sense to simply new() it.

This benchmark instantiates SpaceUnits via constructor and reference:

This benchmark instantiates SpaceUnits via constructor and reference, but also inserts them into an array of SpaceUnits:
