Expand description

Some sort of check on the origin is performed by this object.

Required Associated Types§

A return type.

Required Methods§

Perform the origin check.

Provided Methods§

Perform the origin check.

Returns an outer origin capable of passing try_origin check.

NOTE: This should generally NOT be reimplemented. Instead implement try_successful_origin.

** Should be used for benchmarking only!!! **

Attept to get an outer origin capable of passing try_origin check. May return Err if it is impossible. Default implementation just uses successful_origin().
