Config hot-key for running rust tests in buffer

[dmyyy]

Hello! I came up with a shell command that allows me to run rust unit tests for my current buffer using the new %{buffer_name}.

It works when running it as a command as so:

:sh RUSTFLAGS=-Awarnings cargo test -q -- --nocapture %sh{echo %{buffer_name} | sed -E 's|^src/||; s|/mod\.rs$||; s|\.rs$||; s|/|::|g'}

It uses sed to modify the buffer_name into a module path which is then used as an argument in cargo test. I'm having trouble binding this command to a keybinding in my config. Copy pasting it directly doesn't work correctly. I tried breaking it apart but the config parser doesn't seem very happy with sed quotation marks/escape sequences - would appreciate some pointers.

Current attempt:

[keys.normal.space.t]
# t = [ ':sh RUSTFLAGS=-Awarnings cargo test -q -- --nocapture %sh{echo %{buffer_name} | sed -E "s|^src/||; s|/mod\.rs$||; s|\.rs$||; s|/|::|g"}' ]
t = [
  ":echo %{buffer_name}",
  ":pipe-to sed -E 's|^src/||; s|/mod\.rs$||; s|\.rs$||; s|/|::|g'",
]

It was unhappy with the backslashes - escaping with '\' worked. Here's a keybinding to run all rust unit tests in your current buffer:

[keys.normal.space.t]
t = [
  ":sh RUSTFLAGS=-Awarnings cargo test -q -- --nocapture %sh{echo %{buffer_name} | sed -E 's|^src/||; s|/mod\\.rs$||; s|\\.rs$||; s|/|::|g' }",
]
