}Expand description
Represents a child process spawned into the pty.
Required Methods§
Sourcefn try_wait(&mut self) -> IoResult<Option<ExitStatus>>
fn try_wait(&mut self) -> IoResult<Option<ExitStatus>>
Poll the child to see if it has completed. Does not block.
Sourcefn wait(&mut self) -> IoResult<ExitStatus>
fn wait(&mut self) -> IoResult<ExitStatus>
Blocks execution until the child process has completed.
Sourcefn process_id(&self) -> Option<u32>
fn process_id(&self) -> Option<u32>
Returns the process identifier of the child process, if applicable.
Implementations§
Source§impl dyn Child
impl dyn Child
Sourcepub fn is<__T: Child>(&self) -> bool
pub fn is<__T: Child>(&self) -> bool
Returns true if the trait object wraps an object of type __T.
Sourcepub fn downcast<__T: Child>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>
pub fn downcast<__T: Child>(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.
Sourcepub fn downcast_rc<__T: Child>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>
pub fn downcast_rc<__T: Child>(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.
Sourcepub fn downcast_ref<__T: Child>(&self) -> Option<&__T>
pub fn downcast_ref<__T: Child>(&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.
Sourcepub fn downcast_mut<__T: Child>(&mut self) -> Option<&mut __T>
pub fn downcast_mut<__T: Child>(&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.
