Trait Implementations

impl AirQualityClient for AirQualitySensor<'_>

fn environment_specified(&self, _result: Result<(), ErrorCode>)

Called when the environment specify command has completed.

fn co2_data_available(&self, value: Result<u32, ErrorCode>)

Called when a CO2 or equivalent CO2 (eCO2) reading has completed.

fn tvoc_data_available(&self, value: Result<u32, ErrorCode>)

Called when a Total Organic Compound (TVOC) reading has completed.

impl SyscallDriver for AirQualitySensor<'_>

fn command( &self, command_num: usize, _: usize, _: usize, processid: 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.
