Trait DataSource 

Source 
pub trait DataSource {
    // Required methods
    fn poll(&mut self) -> Result<Snapshot, SourceError>;
    fn signal_process(
        &mut self,
        pid: u32,
        signal: ProcessSignal,
    ) -> Result<(), SourceError>;
}
Expand description

A producer of snapshots, local or remote.

Required Methods§

Source

fn poll(&mut self) -> Result<Snapshot, SourceError>

Takes a new measurement.

Rates (CPU %, throughput, power) cover the time since the previous call, so callers should poll at a steady interval of at least MIN_POLL_INTERVAL.

Source

fn signal_process( &mut self, pid: u32, signal: ProcessSignal, ) -> Result<(), SourceError>

Sends signal to process pid on the monitored host, with the privileges of the user the source runs as.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
