Struct UseId 

pub struct UseId<T, F> { /* private fields */ }

A wrapper that provides identity to a value through a function.

This allows attaching identity behavior to any type by providing a function to extract an ID from the wrapped value.

Implementations

impl<T, F> UseId<T, F>

pub const fn new(value: T, f: F) -> UseId<T, F>

Creates a new UseId instance wrapping the given value and function.

pub fn into_inner(self) -> T

Consumes the wrapper and returns the inner value.

Trait Implementations

impl<T, F> Debug for UseId<T, F>

where T: Debug, F: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T, F> Deref for UseId<T, F>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<UseId<T, F> as Deref>::Target

Dereferences the value.

impl<T, F, Id> Identifiable for UseId<T, F>

where F: Fn(&T) -> Id, Id: Ord + Hash + Clone,

fn id(&self) -> <UseId<T, F> as Identifiable>::Id

Applies the stored function to the wrapped value to generate an ID.

type Id = Id

The type of ID to use, which must implement Hash and Ord traits.
