Rust。請注意，依附元件和「獨特」型別越少越好。理想情況是確保程式碼能剖析部 分原始位元組。 由於 Rust 在 Android 中越來越廣為使用，講者可能可以提到以下議題： • 服務範例：DNS_over_HTTP • 程式庫：Rutabaga 虛擬繪圖介面 • 核心驅動程式：Binder • 韌體：pKVM 韌體 186 第 32 部分 設定 我們會使用 Cuttlefish Android of creating a Binder interface. We're then going to both implement the described service and write client code that talks to that service. 34.1.1 AIDL 介面 您可以使用 AIDL 介面宣告服務的 API： birthday_service/aidl

and has to do with the accept and connect methods. The accept method retrieves a connection to the client that is connecting on the server we just created, while the connect function connects to a server request was now available), accepted the connection, printed the message and waited for the next client. Reading and writing works in the same way. To see this, consider the following simple echo server: com", "github.com", "julialang.org") @async begin conn = connect(hostname, 80) write(conn, "GET / HTTP/1.1\r\nHost:$(hostname)\r\n\r\n") readline(conn, keep=true) println("Finished connection to $(hostname)")
