Struct Scoped

Source 
pub struct Scoped<T: Task = Process>(/* private fields */);
Expand description

Scoped wrapper for a process or job backed by a Zircon handle.

The process or job is killed when the wrapper goes out of scope or the current process panics. See the module-level documentation for more details.

Implementations§

Source§

impl<T: Task> Scoped<T>

Source

pub fn kill(self) -> Result<T, Status>

Kills the process, consuming the Scoped wrapper and returning the inner task object.

Source

pub fn into_inner(self) -> T

Consumes the Scoped wrapper and returns the inner task object. The task will no longer be killed on Drop, but may still be killed on exit.
