Adapter.queueFamilies`.\n+Support for `graphics`, `compute`, and `copy` operations are surfaced by the respective attributes on the QueueFamily.\n+Queue families with `graphics` or `compute` will always have `copy`.\n+There may be queue families in the future like D3D12's video decode queues, which do not support copy operations.\n+If there are any families that support graphics, there is at least one family that supports both compute and graphics.\n+The most capable family is always first in the `Adapter.queueFamilies` list.\n+(It will either be a graphics+compute, or at least compute)\n+Exposed adapters must have at least a compute family.\n+Users can also create `QueueFamily`s.","path":"design/MultipleQueues.md","position":19,"original_position":19,"commit_id":"5fe7a70a2c3e21ff15263d943396d0e024d8d2ac","original_commit_id":"5fe7a70a2c3e21ff15263d943396d0e024d8d2ac","user":{"login":"litherum","id":918903,"node_id":"MDQ6VXNlcjkxODkwMw==","avatar_url":"https://avatars0.githubusercontent.com/u/918903?v=4","gravatar_id":"","url":"https://api.github.com/users/litherum","html_url":"https://github.com/litherum","followers_url":"https://api.github.com/users/litherum/followers","following_url":"https://api.github.com/users/litherum/following{/other_user}","gists_url":"https://api.github.com/users/litherum/gists{/gist_id}","starred_url":"https://api.github.com/users/litherum/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/litherum/subscriptions","organizations_url":"https://api.github.com/users/litherum/orgs","repos_url":"https://api.github.com/users/litherum/repos","events_url":"https://api.github.com/users/litherum/events{/privacy}","received_events_url":"https://api.github.com/users/litherum/received_events","type":"User","site_admin":false},"body":">
