Struct AroState 

pub struct AroState { /* private fields */ }

A type-map service container for dependency injection.

Implementations

impl AroState

pub fn builder() -> AroStateBuilder

Create a new builder for constructing an AroState.

pub fn get<T>(&self) -> Option<Arc<T>>

where T: 'static + ?Sized, Arc<T>: 'static,

Retrieve a registered service by trait type.

pub fn merge(self, other: AroState) -> AroState

Merge another AroState into this one.

pub fn validate_dep<T>(&self) -> Result<(), String>

where T: 'static + ?Sized, Arc<T>: 'static,

Validate that an expected dependency is registered.

Trait Implementations

impl Clone for AroState

fn clone(&self) -> AroState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AroState

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

Formats the value using the given formatter.

impl<T: ?Sized + 'static> FromRef<AroState> for Dep<T>

where Arc<T>: Send + Sync + Clone + 'static,

fn from_ref(state: &AroState) -> Self

Converts to this type from a reference to the input type.

impl<T: ?Sized + 'static> FromRequestParts<AroState> for Dep<T>

where Arc<T>: Send + Sync + Clone + 'static,

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( _parts: &mut Parts, state: &AroState, ) -> Result<Self, Self::Rejection>

Perform the extraction.
