fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<CatalogError> for AkarError

fn from(e: CatalogError) -> Self

Converts to this type from the input type.

impl From<CatalogError> for String

Allow ? in functions still returning Result<T, String>.

fn from(e: CatalogError) -> String

Converts to this type from the input type.

impl From<CatalogError> for BinderError

Allow catalog errors to propagate through the binder.

fn from(e: CatalogError) -> Self
