- Add a check-rustfmt.sh script which checks if the right version of rustfmt is installed. - Run check-rustfmt.sh --install as an install step under travis_wait. This is to work around the issue where cargo takes forever to build rustfmt, causing Travis to terminate the build because it hasn't produced any output for 10 minutes.

# Usage: check-rustfmt.sh [--install]

|

# Check that the desired version of rustfmt is installed.
|

#
|
|
# Rustfmt is still immature enough that its formatting decisions can change
|
|
# between versions. This makes it difficult to enforce a certain style in a
|
|
# test script since not all developers will upgrade rustfmt at the same time.
|
|
# To work around this, we only verify formatting when a specific version of
|
|
# rustfmt is installed.
|
|
#
|
|
# Exits 0 if the right version of rustfmt is installed, 1 otherwise.
|
|
#
|
|
# With the --install option, also tries to install the right version.
|
|
|
|
# This version should always be bumped to the newest version available.
