Struct Console 

pub struct Console<'a> { /* private fields */ }

Implementations

impl<'a> Console<'a>

pub fn new( uart: &'a dyn UartData<'a>, tx_buffer: &'static mut [u8], rx_buffer: &'static mut [u8], grant: Grant<App, UpcallCount<{ upcall::COUNT }>, AllowRoCount<{ ro_allow::COUNT }>, AllowRwCount<{ rw_allow::COUNT }>>, ) -> Console<'a>

Trait Implementations

impl ReceiveClient for Console<'_>

fn received_buffer( &self, buffer: &'static mut [u8], rx_len: usize, rcode: Result<(), ErrorCode>, error: Error, )

A call to [Receive::receive_buffer] completed.

fn received_word(&self, _word: u32, _rval: Result<(), ErrorCode>, _error: Error)

A call to [Receive::receive_word] completed.

impl SyscallDriver for Console<'_>

fn command( &self, cmd_num: usize, arg1: usize, _: usize, processid: ProcessId, ) -> CommandReturn

Initiate serial transfers

command_num

• 0: Driver existence check.
• 1: Transmits a buffer passed via allow, up to the length passed in arg1
• 2: Receives into a buffer passed via allow, up to the length passed in arg1
• 3: Cancel any in progress receives and return (via callback) what has been received so far.

fn allocate_grant(&self, processid: ProcessId) -> Result<(), Error>

Request to allocate a capsule’s grant for a specific process.

fn allow_userspace_readable( &self, app: ProcessId, which: usize, slice: ReadWriteProcessBuffer, ) -> Result<ReadWriteProcessBuffer, (ReadWriteProcessBuffer, ErrorCode)>

System call for a process to pass a buffer (a [UserspaceReadableProcessBuffer]) to the kernel that the kernel can either read or write. The kernel calls this method only after it checks that the entire buffer is within memory the process can both read and write.

impl TransmitClient for Console<'_>

fn transmitted_buffer( &self, buffer: &'static mut [u8], _tx_len: usize, _rcode: Result<(), ErrorCode>, )

A call to [Transmit::transmit_buffer] completed.

fn transmitted_word(&self, _rval: Result<(), ErrorCode>)

A call to [Transmit::transmit_word] completed.
