Module error 

One error type for every handler. Spec section 12: the web side shows friendly error pages, errors inside htmx partials show inline, and a Postgres outage is a 503 page.

AppError::into_response only records what went wrong (an ErrorInfo extension); the error_pages middleware, which can see whether the request came from htmx, turns that into either a full page or an inline fragment.

Structs

ErrorInfo

What went wrong, attached to an error response for error_pages to render.

Enums

AppError

Functions

error_pages

Renders ErrorInfo responses as a full page, or as an inline fragment for htmx.

is_unavailable

Connection-level failures mean Postgres is down or unreachable: a 503, not a 500.

not_found

The router’s fallback: unknown paths get the friendly 404.
