Trait extendr_api::prelude::RawDataSubst

pub trait RawDataSubst<A>: RawData {
    type Output: RawData<Elem = A>;

    // Required method
    unsafe fn data_subst(self) -> Self::Output;
}

Array representation trait.

The RawDataSubst trait maps the element type of array storage, while keeping the same kind of storage.

For example, RawDataSubst<B> can map the type OwnedRepr<A> to OwnedRepr<B>.

Required Associated Types

type Output: RawData<Elem = A>

The resulting array storage of the same kind but substituted element type

Required Methods

unsafe fn data_subst(self) -> Self::Output

Unsafely translate the data representation from one element representation to another.

Safety

Caller must ensure the two types have the same representation.

Object Safety

This trait is not object safe.
