Enum ndarray::CowRepr

source · [−]

pub enum CowRepr<'a, A> {
    View(ViewRepr<&'a A>),
    Owned(OwnedRepr<A>),
}

Expand description

CowArray’s representation.

Don’t use this type directly—use the type alias CowArray for the array type!

Variants

`View(ViewRepr<&'a A>)`

Borrowed data.

`Owned(OwnedRepr<A>)`

Owned data.

Implementations

source

impl<'a, A> CowRepr<'a, A>

source

pub fn is_view(&self) -> bool

Returns true iff the data is the View variant.

source

pub fn is_owned(&self) -> bool

Returns true iff the data is the Owned variant.
