Adds an alternative HTTPDoer backed by valyala/fasthttp for high-throughput
bots. Cuts per-call allocs from 102 to 56 in the cross-library bench
(within 8 of telego, which uses fasthttp by default), and per-call bytes
from 11.1 KiB to 6.6 KiB.
bot := client.New(token,
client.WithHTTPClient(client.NewFastHTTPDoer()),
)
Implementation notes:
- Wraps *fasthttp.Client behind the existing HTTPDoer (Do *http.Request)
interface, so RetryDoer, custom transports, observability middleware,
and the 1428 generated tests all keep working as-is.
- Translates *http.Request -> fasthttp.Request once per call and
returns a *http.Response whose Body releases the pooled fasthttp
response on Close (net/http contract).
- Recognises the bufferReadCloser / readerReadCloser shapes produced
by buildRequest and passes their underlying bytes straight to
SetBodyRaw -- no io.ReadAll, no copy.
- Honours ctx.Deadline via DoDeadline, falls back to WithFastHTTPReadTimeout
when no deadline is set. fasthttp.ErrTimeout maps to
context.DeadlineExceeded for errors.Is compatibility.
Default stays net/http: fasthttp is HTTP/1.1 only, doesn't compose with
the http.RoundTripper middleware ecosystem, and most users don't have
the throughput to notice. Bots making thousands of API calls/sec should
opt in.
Multipart/file-upload path remains on net/http per the agreed scope --
the perf bottleneck was JSON-method round-trip, not file uploads.
Time numbers in the report deferred until a quiet-system bench run;
allocs/bytes numbers (which are deterministic per code path) are
already updated.
