bigdecimal 0.4.1

# Gitlab CI Config
# ================
#
# Defines jobs for checking/building/testing various
# configurations of the BigDecimal crate.
#
# Always tests against stable and MinimumSupportedRustVersion (1.43)
# Other random versions are available, requiring manual action to run.
#
# Most jobs are run upon custom rust containers I try to keep updated:
#    https://gitlab.com/akubera/containers/-/blob/master/akubera-rust/Dockerfile.in
#    https://hub.docker.com/r/akubera/rust/tags
#
# A coverage report is done via one of my rust-kcov or rust-grcov containers:
#    https://gitlab.com/akubera/containers/-/blob/master/rust-kcov/Dockerfile.in
#    https://gitlab.com/akubera/containers/-/blob/master/rust-grcov/Dockerfile.in
#
# A cargo:benchmark job is available, which saves a criterion report to gitlab,
# manualy activated and of dubious reliability without control of target machine.
