Once you bind the associated types explicitly, the requirements using those associated types need to match the bound types otherwise the type checker will emit an error. If you have default associated types and default implementations, but then bind the associated types differently and do not update your type-specific implementations to use those other types, you will get an error message. This is how explicitly specifying associated types works today.</div><div class="" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><br class=""></div><div class="" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;">Austin</div></div></blockquote></div><br class=""><div class="">The problem is that it doesn’t give me any error message.
