Struct metrics_util::CompositeKey [−][src]
pub struct CompositeKey(_, _);
A composite key that stores both the metric key and the metric kind.
This type is intended to be used by recorders that internally take advantage of
the provided Registry
type when also using
Handle
.
Since handles are opaque, having the standard key by itself could lead to two
different metric kinds tryin to use the same key, calling read or write methods
that inevitably panic. With CompositeKey
, the kind can tied to the underlying
handle, ensuring parity between the two.
