Enum ServiceKey 

pub enum ServiceKey {
    Type(TypeId),
    Named {
        type_id: TypeId,
        name: String,
    },
}

Service key for identifying and distinguishing different services Supports both type-based keys and named keys

Variants

Type(TypeId)

Type-based key - uses TypeId as unique identifier

Named

Name-based key - combines TypeId and name as unique identifier

Fields

type_id: TypeId

name: String

Implementations

impl ServiceKey

pub fn of_type<T: 'static>() -> Self

Create a type-based service key

pub fn named<T: 'static>(name: impl Into<String>) -> Self

Create a name-based service key

pub fn type_id(&self) -> TypeId

Get type ID

pub fn name(&self) -> Option<&str>

Get name (if any)

pub fn is_named(&self) -> bool

Check if it’s a type-based key

pub fn type_name(&self) -> &'static str

Get type name

Trait Implementations

impl Clone for ServiceKey

fn clone(&self) -> ServiceKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServiceKey

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

Formats the value using the given formatter.

impl Display for ServiceKey

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

Formats the value using the given formatter.

impl Hash for ServiceKey

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 PartialEq for ServiceKey

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.
