Struct rocket_db_pools::figment::value::Tag
[−]pub struct Tag(_);
Expand description
An opaque, unique tag identifying a value’s Metadata
and profile.
A Tag
is retrieved either via Tagged
or Value::tag()
. The
corresponding metadata can be retrieved via Figment::get_metadata()
and
the profile vile Tag::profile()
.
