pub fn id(&self) -> u32

Return the platform process identifier.

pub fn poll(&mut self) -> Result<ProcessUpdate>

Drain retained output and check for process completion without waiting.

Trait Implementations

impl Debug for RunningProcess

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

Formats the value using the given formatter.

impl Drop for RunningProcess

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
