Implementations

impl SystemInfo

pub fn collect(opts: CollectOptions) -> Result<SystemInfo, Error>

Collects system information using sysinfo and environment probes.

This method aggregates data from the operating system, hardware, and current user environment into a SystemInfo struct.

Trait Implementations

impl Debug for SystemInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
