Struct index_ext::tag::TagNamed

pub struct TagNamed<T> { /* private fields */ }

Expand description

A unique tag, ‘named’ by its type parameter.

Note that this type is safe to construct, but it is not safe to tag a slice or index with it. The user is responsible for ensuring the uniqueness of the type parameter, which is necessary for the soundness of wrapping an index or slice.

Implementations§

impl<T> TagNamed<T>

pub const fn new(t: T) -> Self

Create a new named tag.

The instance is only to be encouraged to only use types private to your crate or module, this method immediately forgets the instance which is currently required for constness.
