[−][src]Struct metered::common::ErrorCount
A metric counting how many times an expression typed std Result
as returned an Err
variant.
This is a light-weight metric.
By default, ErrorCount
uses a lock-free u64
Counter
, which makes sense in multithread scenarios. Non-threaded applications can gain performance by using a std::cell:Cell<u64>
instead.
