Thanks for the report. This looks like a problem with the linemux dependency. I don't have much time to look at code atm so if anyone wants to try giving this let us know in a reply.

Otherwise I'll get to it eventually!

is there a dependency history ?
should i consider simply using a different tag ?

changed linemux version = "0.1.3" to "0.2.3" for Cargo.toml and Cargo.toml.orig and now it builds, error now on termion-rs, my guess is the dependency issue now ripples onwards beyond linemux

I'd look at recent linemux releases and step back through them. IIRC we had a similar issue not long ago, but I'm not certain if it was fixed in linemux. I may have opened an issue there for it.

Sorry to be vague.

2 more corrections, sorry, i don't have experience modifying code using rust or git

rewrite in both src/bin/logtail-crossterm.rs and src/bin/logtail-termion.rs

use tokio::stream::StreamExt;
as
use tokio_stream::StreamExt;

logtail compiles and installs again after changing dependendy for linemux and adding dependencies for tokio-stream-ext and correcting the use of tokio::stream to tokio_stream

Cargo.toml now looks like
. . .
[dependencies.linemux]
version = "0.2.3"
. . .
[dependencies.tokio-stream]
version = "0.1.7"

[dependencies.tokio-stream-ext]
version = "0.1.5"

rewrite in both src/bin/logtail-crossterm.rs and src/bin/logtail-termion.rs

use tokio::stream::StreamExt;
as
use tokio_stream::StreamExt;

Damn. I've not tested. This i fail to understand / resolve. I don't have time to dig into the code here at this point. Neither do i think i can make meaningful observations due to a lack of experience and understanding.

Looks like useful progress thanks. You can enable features like the rt asked for there in Cargo.toml (I forget the syntax but there might be an example there). No worries if you want to leave it at that, I may find time to look at it over the next days. Thanks for having a go.

Tried a bit more, no progress. The code for blocking.rs has two main fuctions/macros(?)

one is cfg_rt! and the other is cfg_not_rt!

the latter is where the message 'requires the rt Tokio feature flag' originates from.

I don't see where blocking.rs is called from in the first place to arrive at this condition.

My assumption is i may have skipped a few releases in the Cargo.toml modifications and this breaks stuff.
