Implementations§

Source §

impl dyn ModelField

Source

pub fn is<T: ModelField>(&self) -> bool

Returns true if the boxed type is the same as T

Source

pub fn downcast_ref<T: ModelField>(&self) -> Option<&T>

Returns some reference to the boxed value if it is of type T, or None if it isn’t.

Source

pub unsafe fn downcast_ref_unchecked<T: ModelField>(&self) -> &T

Returns a reference to the boxed value, blindly assuming it to be of type T. If you are not absolutely certain of T, you must not call this.

Source

pub fn downcast_mut<T: ModelField>(&mut self) -> Option<&mut T>

Returns some mutable reference to the boxed value if it is of type T, or None if it isn’t.

Source

pub unsafe fn downcast_mut_unchecked<T: ModelField>(&mut self) -> &mut T

Returns a mutable reference to the boxed value, blindly assuming it to be of type T. If you are not absolutely certain of T, you must not call this.
