pub struct ContextBuilder { /* private fields */ }

Implementations

impl ContextBuilder

pub fn config(self, config: Config) -> Self

pub fn state<T: Send + Sync + 'static>(self, value: T) -> Self

Register a service. One value per type; registering twice replaces.

pub fn registered<T: Send + Sync + 'static>(&self) -> Option<&T>

What was registered under this type, before the context is built.

The console commands need it: migrate used to build a second database connection from DATABASE_URL, ignoring the one the application had already opened. For an application whose handle comes from anywhere else — a second key, a vault lease, a tenant lookup — that is a migration run against the wrong database, or against none.

pub fn has_state<T: Send + Sync + 'static>(&self) -> bool

Whether something of this type has already been registered.

For the case where the framework would otherwise supply a default and quietly replace what the application built for itself — see how App decides whether to construct a view engine.
