Description

It is great that recent versions of fasthttp have trailer support, but it is more difficult and awkward to use. We should have minimal features like so:

  • PeekTrailer
  • PeekAllTrailer see #1394

It is tricky because SetTrailer isn't setting for a single value, rather all values. It would be nicer to have parity for apis to set/add and del, as well.

See https://github.com/mosn/pkg/issues/66

Contributor guide

Research direction
The issue requests new trailer functions (PeekTrailer, PeekAllTrailer) to improve usability. Reference existing issue #1394 and the external mosn/pkg issue for context. Study current trailer implementation in fasthttp (e.g., Response.SetTrailer), then implement the requested peek functions and potentially set/add/del parity functions. Ensure API consistency and performance.
