RUST_LOG_STYLE
The RUST_LOG_STYLE variable sets the style of printed records. It has three variants:
- auto: Tries to use the style characters
- always: Always uses the style characters
- never: Turns off the style characters
See the following example:
RUST_LOG_STYLE=auto cargo run
I recommend that you use the never value if you redirect the stderr output a file or if you want to use grep or awk to extract values with special patterns.
