Install fails with rustc 1.74.0 #252

Closed GregoryTravis closed 8 months ago

GregoryTravis commented 8 months ago

I'm running rustc 1.74.0 on MacOS 12.6.3. I'm getting the error below. Is there a rustc version requirement for this crate?

$ cargo install cargo-show-asm

Version published on crates.io uses return position impl trait in trait - this requires 1.75.0. You can install one of the earlier versions - 0.2.29 should work, install version from github or update your compiler. Are there any reasons you are not on the latest version of rustc?

I don't think I have any reason not to update rust so I'll try that.

I'm assuming that's no longer a problem.
