span, currently in rustc, configures the hygiene information
for this identifier.
As of this time
Span::call_site() explicitly opts-in to “call-site” hygiene
meaning that identifiers created with this span will be resolved as if they were written
directly at the location of the macro call, and other code at the macro call site will be
able to refer to them as well.
Later spans like
Span::def_site() will allow to opt-in to “definition-site” hygiene
meaning that identifiers created with this span will be resolved at the location of the
macro definition and other code at the macro call site will not be able to refer to them.
Due to the current importance of hygiene this constructor, unlike other
tokens, requires a
Span to be specified at construction.

Prints the identifier as a string that should be losslessly convertible back into the same identifier.
