Trait ChildKiller 

pub trait ChildKiller:
    Debug
    + Downcast
    + Send {
    // Required methods
    fn kill(&mut self) -> IoResult<()>;
    fn clone_killer(&self) -> Box<dyn ChildKiller + Send + Sync>;
}

Represents the ability to signal a Child to terminate.

Required Methods

fn kill(&mut self) -> IoResult<()>

Terminate the child process.

fn clone_killer(&self) -> Box<dyn ChildKiller + Send + Sync>

Clone an object that can be split out from the Child in order to send it signals independently from a thread that may be blocked in .wait.

Implementations

impl dyn ChildKiller

pub fn is<__T: ChildKiller>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: ChildKiller>( self: Box<Self>, ) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: ChildKiller>( self: Rc<Self>, ) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: ChildKiller>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: ChildKiller>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
