Unable to parse lock file

[jcholder-thoughtworks]

Howdy! I get the following error when I try to run cargo instruments (no arguments):

Failed failed to parse lock file at: /[redacted but correct]/Cargo.lock.

The Cargo.lock is freshly generated from a new project created a couple weeks ago.

The full Cargo.lock file.

cargo version: cargo 1.42.0-nightly (9d32b7b01 2020-01-26).
rustc version: rustc 1.42.0-nightly (3761dcd34 2020-01-28).

Environment: macOS Mojave 10.14.6.

Initial guess is that the cargo crate in this crate needs to be updated to the current version, 0.42.0.

Glad to provide additional info as needed. Thanks!

Heads up that cargo versions 0.36.0 and higher have breaking changes to the API.

@jcholder-thoughtworks gotcha, thanks for opening the issue. To check my understanding, this is about the new lockfile format; the new cargo can work with the old format, but old cargo doesn't work with the new format?

Just want to make sure that updating cargo doesn't have any unintended consequences.

@jcholder-thoughtworks I've just pushed a patch would you like to try it out? You'll have to check it out locally and then do cargo install --force --path=. (assuming this is executed from the source directory). If this is working for you, I'll do a crates.io release.

@cmyr Success! Thanks!
