Struct ServiceProvider

pub struct ServiceProvider(pub Services);

An extractor that provides access to application services in route handlers.

This extractor simplifies access to application services by extracting them from request extensions. It serves as a convenient wrapper around the Services type without performing any additional validation or authentication.

Fields

• 0 - The Services instance containing all application services

Example

async fn route_handler(
    ServiceProvider(services): ServiceProvider
) -> Result<impl Response, Error> {
    // Use services directly
    let some_data = services.some_service.do_something().await?;
    Ok(some_data)
}

Tuple Fields

0: Services

Trait Implementations

impl<S> FromRequestParts<S> for ServiceProvider

where S: Send + Sync,

Implementation of FromRequestParts to enable automatic extraction of services from request extensions.

Errors

Returns Error::InternalServerErrorWithContext if:

• Services are not found in request extensions
• Extension extraction fails

type Rejection = Error

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

fn from_request_parts<'life0, 'life1, 'async_trait>( parts: &'life0 mut Parts, state: &'life1 S, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Perform the extraction.
