Implementations

impl<'a, DateTime: DateTime<'a>> DateTimeCapsule<'a, DateTime>

pub fn new( date_time: &'a DateTime, grant: Grant<AppData, UpcallCount<1>, AllowRoCount<0>, AllowRwCount<0>>, ) -> DateTimeCapsule<'a, DateTime>

Trait Implementations

impl<'a, DateTime: DateTime<'a>> DateTimeClient for DateTimeCapsule<'a, DateTime>

fn get_date_time_done(&self, datetime: Result<DateTimeValues, ErrorCode>)

Called when a date time reading has completed. Takes Ok(DateTime) of current date and passes it when scheduling an upcall. If an error is encountered it takes an Err(ErrorCode)

fn set_date_time_done(&self, result: Result<(), ErrorCode>)

Called when a date is set Takes Ok(()) if time is set correctly. Takes Err(ErrorCode) in case of an error

impl<'a, DateTime: DateTime<'a>> SyscallDriver for DateTimeCapsule<'a, DateTime>

fn command( &self, command_number: usize, r2: usize, r3: usize, process_id: ProcessId, ) -> CommandReturn

System call for a process to perform a short synchronous operation or start a long-running split-phase operation (whose completion is signaled with an upcall). Command 0 is a reserved command to detect if a peripheral system call driver is installed and must always return a CommandReturn::success.

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.
