pub struct UnsizeableMut<'a> { /* private fields */ }Expand description
Mutable reference holder, returned by TypeInfoDynamic::field_mut method
Can be downcasted to underlying type if underlying type is “nameable”
Implementations§
Source§impl<'a> UnsizeableMut<'a>
impl<'a> UnsizeableMut<'a>
Sourcepub fn downcast_mut<T>(&self) -> Option<&'a mut T>where
T: 'static,
pub fn downcast_mut<T>(&self) -> Option<&'a mut T>where
T: 'static,
Attempts to downcast field to mutable reference of particular type
You need to be able to name this type in compile-time
If T doesn’t match actual type, Option::None will be returned
