It looks like there's not a builtin log format that recognizes these types of messages. I don't have any time right this second, but can work on it tonight/tomorrow. If you want to give it a go, try the regex101 integration for creating a log format. That's what I will be doing. |

Okay, thanks for the help to get started. And of course, thanks for sharing lnav with the world. Here are my REs I think mentioning PCRE2 in the (awesome) docs would be a nice small tweak.

That's awesome! I guess you didn't like the names with rust_ at the front? No matter, it's awesome they are in the program now. |

I am new to lnav, but it looks pretty slick!
I'd like it use it with Rust, and it seems
env_loggeris one of the most popular formatters for the Rustlogcrate and logging ecosystem.It's default logs look like:
I did some investigating to see if there was maybe a pre-existing format to use. Syslog could work, but it seems less than ideal to me, honestly.
Anyway I'd like to hear if there is a good or recommended setup for Rust that I somehow overlooked.
Thanks
