Per-phase timing for proxy requests.
Durations are measured directly around the Mint transport calls using
System.monotonic_time/1: connect_us (TCP + TLS handshake), send_us
(request send) and recv_us (response receive). There is no connection
pool, so queue_us and idle_time_us are always nil and
reused_connection? is always false.
Populated only when collect_timing: true is passed to Philter.proxy/2;
otherwise every phase field is nil.
Summary
Functions
Builds a phase-timing map from measured microsecond durations.
Functions
@spec new(non_neg_integer() | nil, non_neg_integer() | nil, non_neg_integer() | nil) :: t()
Builds a phase-timing map from measured microsecond durations.
queue_us and idle_time_us are always nil and reused_connection? is
always false because the Mint transport establishes a fresh connection per
request with no pool.
