Implementations§

source§

impl dyn MacroError

source

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

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

source

pub fn downcast<__T: MacroError>(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.

source

pub fn downcast_rc<__T: MacroError>(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.

source

pub fn downcast_ref<__T: MacroError>(&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.

source

pub fn downcast_mut<__T: MacroError>(&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.
