Trait tuple::TupleElements [−] [src]

pub unsafe trait TupleElements: Sized {
    type Element;

    const N: usize;

    fn get(&self, n: usize) -> Option<&Self::Element>;

    fn get_mut(&mut self, n: usize) -> Option<&mut Self::Element>;

    fn from_iter<I>(iter: I) -> Option<Self>
    where
        I: Iterator<Item = Self::Element>;

    fn elements(&self) -> Elements<&Self> { ... }

    fn elements_mut(&mut self) -> Elements<&mut Self> { ... }

    fn into_elements(self) -> IntoElements<Self> { ... }
}

This trais is marked as unsafe, due to the requirement of the get_mut method, which is required work as an injective map of index -> element

A tuple must not have a Drop implementation.
