Enum Hook 

#[non_exhaustive]
pub enum Hook {
    Routed,
    Finish,
    BeforeRender,
}

A named point in the pipeline where registered code runs, only for the routes it registered for. A route with no hooks pays nothing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Routed

After the access check passed, before the handler: locale, feature flags, an A/B variant. An error ends the request.

Finish

After the handler succeeded, before the reply leaves: add headers. An error replaces the reply with the error page.

BeforeRender

Inside Cx::render, before the engine runs: choose a variant, add headers. A hook that renders does not run these hooks again.
