Struct AppState 

pub struct AppState {
    pub pool: Option<Pool<AsyncPgConnection>>,
}

Shared application state passed to all route handlers.

Holds framework-managed resources such as the database connection pool. Axum requires handler state to be Clone, so internal resources use Arc or are already cheaply cloneable (deadpool::Pool is Arc-wrapped internally).

This struct is normally constructed by app::AppBuilder::run and should not need to be created manually. It is public so that custom Axum extractors can access framework resources via State<AppState>.

Examples

use autumn_web::AppState;

// State without a database (e.g., for testing)
let state = AppState { pool: None };

Fields

pool: Option<Pool<AsyncPgConnection>>

Database connection pool, or None when no database.url is configured.

Trait Implementations

impl Clone for AppState

fn clone(&self) -> AppState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppState

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

Formats the value using the given formatter.

impl FromRequestParts<AppState> for Db

type Rejection = AutumnError

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: &AppState, ) -> Result<Self, Self::Rejection>

Perform the extraction.
