-// To introduce a new mojom type, you must define (partial or full) template |
-// specializations for the following traits templates, which operate on the C++ |
-// wrapper types representing a mojom type: |
-// - WrapperTraits: provides a |DataType| typedef which points to the |
-// serialized data type. |
-// - ValueTraits: provides an |Equals()| method for comparing the two wrapper |
-// values of the same type. |
-// |
-// Currently, full specializations of WrapperTraits are generated for mojo |
-// structs in their generated `.mojom.h`. In contrast, WrapperTraits for Unions |
-// don't need to be auto-generated because their underlying DataType can be |
-// accessed without dependency issues -- a catch-all WrapperTraits for unions is |
-// instead defined here. |

-// parameters, provide a default "typename Enable = void" template parameter, |
-// and have specializations define their own Enable expressions (similar to how |
-// ValueTraits is). |
