Struct TypedId 

pub struct TypedId<I, T>(pub I, _);

A generic type-checked wrapper around a generic identifier type

Tuple Fields

0: I

Implementations

impl<I, T> TypedId<I, T>

pub fn new(id: I) -> Self

Creates a new typed id with an underlying ID type of I

pub fn convert<B: From<I>>(self) -> B

The method explicitly converts between typed ids.

use typed_id::TypedId;
let a_id: TypedId<u32, A> = 42.into();
let b_id: TypedId<u32, B> = a_id.convert();

Note, From can not be implemented here. We can’t specify that two generic types, A and B, are distinct. If we try, this fails to compile.

impl<I, A, B> From<TypedId<I, A>> for TypedId<I, B> {
  fn from(other: TypedId<I, A>) -> TypedId<I, B> {
    other.0.into()
  }
}

Trait Implementations

impl<I: Clone, T> Clone for TypedId<I, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn default() -> Self

Returns the “default value” for a type.

impl<I, T> Deref for TypedId<I, T>

type Target = I

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<I: Display, T> Display for TypedId<I, T>

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

Formats the value using the given formatter.

impl<I, T> From<I> for TypedId<I, T>

Converts to this type from the input type.

impl<I: Hash, T> Hash for TypedId<I, T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I: Ord, T> Ord for TypedId<I, T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<I: PartialEq, T> PartialEq for TypedId<I, T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<I: PartialOrd, T> PartialOrd for TypedId<I, T>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
