Struct QueryState 

pub struct QueryState<S = SessionContext>
where
    S: QuerySession,
{
    pub query_context: QueryContext<S>,
}

State required by the API handlers.

Wraps a QueryContext and can be extracted from your application state using axum’s FromRef pattern.

Example

use axum::extract::FromRef;
use stately_arrow::{QueryContext, QuerySession, QueryState};

#[derive(Clone)]
pub struct AppState {
    pub query_context: QueryContext<MySession>,
    pub other_field: String,
}

impl FromRef<AppState> for QueryState<MySession> {
    fn from_ref(state: &AppState) -> Self {
        Self::new(state.query_context.clone())
    }
}

Fields

query_context: QueryContext<S>

The query context containing session and registry.

Implementations

where S: QuerySession + Clone,

fn clone(&self) -> QueryState<S>

Returns a duplicate of the value.

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