Struct SysmontapService 

pub struct SysmontapService<S> { /* private fields */ }

Connect and start a sysmontap CPU monitoring session.

Returns an async stream of CpuSample values.

Implementations

impl<S: AsyncRead + AsyncWrite + Unpin + Send> SysmontapService<S>

pub async fn start( stream: S, config: &SysmontapConfig, sys_attrs: Option<Vec<Value>>, proc_attrs: Option<Vec<Value>>, ) -> Result<Self, DtxError>

Initialize sysmontap on an already-connected instruments stream.

sys_attrs and proc_attrs are optional attribute lists from the deviceinfo service. Pass None to use defaults (works on iOS 17+; older iOS may need them).

pub async fn next_cpu_sample(&mut self) -> Result<Option<CpuSample>, DtxError>

Receive the next CPU sample from the device. Blocks until a sample arrives.

pub async fn next_process_snapshot( &mut self, proc_attr_names: &[String], ) -> Result<Option<ProcessSample>, DtxError>

Receive the next per-process snapshot from sysmontap.

proc_attr_names should be the ordered list of attribute names matching the procAttrs config (e.g. from DeviceInfoClient::process_attributes()). Each process’s values array is zipped with these names.

pub async fn stop(&mut self) -> Result<(), DtxError>

Stop the monitoring session.
