-## Peformance
-
-The macro can optimize away code, short circuit fast paths and generate a Fast
-API impl.
-
-Cases where code is optimized away:
-
-- `-> ()` skips serde_v8 and `rv.set` calls.
-- `-> Result<(), E>` skips serde_v8 and `rv.set` calls for `Ok()` branch.
-- `-> ResourceId` or `-> [int]` types will use specialized method like
-  `v8::ReturnValue::set_uint32`. A fast path for SMI.
-- `-> Result<ResourceId, E>` or `-> Result<[int], E>` types will be optimized
-  like above for the `Ok()` branch.
-
-### Fast calls
-
-The macro will infer and try to auto generate V8 fast API call trait impl for
-`sync` ops with:
-
-- arguments: integers / `&mut OpState`
-- return_type: integers
-
-The `#[op(fast)]` attribute can be used to enforce fast call generation at
-compile time.
-
-Trait gen for `async` ops & a ZeroCopyBuf equivalent type is planned and will be
-added soon.
