Metadata for a service token binding

Contains compile-time information about a token-to-implementation binding for use in dependency resolution and validation.

Fields

token_type_id: TypeId

The token type identifier

token_type_name: &'static str

The token type name (for debugging)

service_type_id: TypeId

The service type identifier

service_type_name: &'static str

The service type name (for debugging)

impl_type_id: TypeId

The implementation type identifier

impl_type_name: &'static str

The implementation type name (for debugging)

name: Option<String>

Optional named identifier for multiple implementations

Implementations

impl TokenBinding

pub fn new<Token, Impl>() -> Self

where Token: ServiceToken, Impl: Send + Sync + 'static,

Create a new token binding

pub fn named<Token, Impl>(name: impl Into<String>) -> Self

where Token: ServiceToken, Impl: Send + Sync + 'static,

Create a named token binding

pub fn to_service_id(&self) -> ServiceId

Create a ServiceId for this token binding

pub fn matches_token<Token: ServiceToken>(&self) -> bool

Check if this binding matches a token type

pub fn validate_implementation<Token, Impl>() -> Result<(), String>

where Token: ServiceToken, Impl: Send + Sync + 'static,

Validate that the implementation can be cast to the service type

This performs compile-time type checking to ensure the implementation actually implements the service trait.

Trait Implementations

impl Clone for TokenBinding

fn clone(&self) -> TokenBinding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenBinding

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

Formats the value using the given formatter.
