wrong match in ale#path#IsBufferPath for rust linter

[lovebug356]

Information

VIM version

NVIM v0.3.1
Build type: Release
Operating System: macOS

What went wrong

The cargo linter, with clippy enabled, generates json lines with spacial "file_name" entries. See this example:

...
    "spans": [
      {
        "file_name": "<::alloc::macros::vec macros>",
        "byte_start": 197,
        "byte_end": 220,
...

when a buffer is checked to have this file_name with ale#path#IsBufferPath, it always returns true. The current implementation of ale#path#IsBufferPath accepts all names starting with a "<" under the assumption that it is a name for stdin.

Do you have any advice on how to interpret filenames like <::alloc::macros::vec macros>? Can we assume that anything like that doesn't match something in the buffer?

While attempting to solve #1570 I came across this issue. I've done a brief search for documentation by reading through the seemingly relevant parts of https://doc.rust-lang.org/, but failed to see any mention of clippy generating these spacial "file_name" entries. Do we know if that behavior is documented somewhere?

Is asked on urlo about this, and it seems this was a temporary thing which no longer happens. Details are in the linked thread, but the TL;DR is this ticket can be closed.
