error: multiple applicable items in scope

• Way Cooler version 0.8.0
• rust 1.30.0
• buildlog: https://build.opensuse.org/package/live_build_log/X11:windowmanagers/way-cooler/openSUSE_Tumbleweed/x86_64

It seems that way-cooler 0.8.0 doesn't build on openSUSE Tumbleweed anymore. I guess this is due to an update of rust in the distro.

petgraph/petgraph#223
Seems like your build system uses aho-corasick v0.5.3 instead of v0.6.9.

[AdminXVII]

A push to crates.io would be required.

[jubalh]

A push to crates.io would be required.

From whom?

[AdminXVII]

Probably from @Timidger

[Timidger]

I have published a new crates.io version (v0.8.1) to address this.

[jubalh]

Thanks for acting so quickly.

[Timidger]

No problem, no Thanksgiving is complete without a working Way Cooler installation 😉
