Pull request overview

This PR updates infra::StdStringInputStream / StdStringInputStreamReader to accept and store std::string_view, allowing the stream to operate on non-owning string views instead of requiring std::string references.

Changes:

  • Switch StdStringInputStreamReader constructor and backing storage from const std::string& to std::string_view.
  • Switch StdStringInputStream constructors to accept std::string_view.
  • Add/update includes needed for std::string_view and related types.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 1 comment.

File Description
infra/stream/StdStringInputStream.hpp Updates public API and reader storage to std::string_view.
infra/stream/StdStringInputStream.cpp Updates constructor definitions to match the new std::string_view-based API.
