rls could not compile clap

[mooreryan]

rls in Visual Studio Code is unable to compile clap. Here is some info on the problem. Let me know if there is any other info that might help!

Reproducing error

Make a project.

cargo new snazzy_proj

Add clap to Cargo.toml

[dependencies]
clap = "2.33"

Then rls does its thing and gives this error message:

Could not compile `clap`.

Note that building the program with cargo run works fine.

Versions

I updated everything to be sure it wasn't a problem there. Here are the versions of everything....

Visual Studio Code: Version 1.33.1 (1.33.1) -- 51b0b28134d51361cf996d2f0a1c698247aeabd8

I ran rustup update just to be sure that wasn't the problem.

stable-x86_64-apple-darwin updated - rustc 1.34.1 (fc50f328b 2019-04-24)
nightly-x86_64-apple-darwin updated - rustc 1.36.0-nightly (8dd4aae9a 2019-05-04)

Also, updated the Visual Studio Code rls plugin to the latest version (v0.6.1).

Sounds like the bitflags 1.0.5 issue see #1449 (comment)

[mooreryan]

You're right, as a workaround locking bitflags to 1.0.4 as in bitflags/bitflags#177 fixes things.

[alexheretic]

With 1.0.5 yanked discussing the bug in rls can be done in #1449 so I'll close this
