Description
It would be nice if rust-mode allowed formatting only specific lines of a file, analogously to clang-format's clang-format-region.
The necessary support to format only certain parts of a file is already present upstream in rustfmt by using the file_lines command line argument.

Research direction
Start by locating rust-mode’s existing rustfmt entry point and compare the requested behavior with clang-format-region. Use rustfmt’s file_lines command-line argument to format only the selected lines, and verify that the new rust-format-region function formats the region without changing unrelated lines.
