# This workflow runs whenever a PR is opened or updated, or a commit is pushed to main. It runs | |
# several checks: | |
# - fmt: checks that the code is formatted according to rustfmt | |
# - clippy: checks that the code does not contain any clippy warnings | |
# - doc: checks that the code can be documented without errors | |
# - hack: check combinations of feature flags | |
# - msrv: check that the msrv specified in the crate is correct | |
# - semver: check API changes for semver violations. | |
# - minimal: runs "cargo check" with the minimal versions of the dependencies that satisfy the | |
# requirements of this crate, and its dependencies | |

# This action chooses the oldest version of the dependencies permitted by Cargo.toml to ensure | |
# that this crate is compatible with the minimal version that this crate and its dependencies | |
# require. This will pickup issues where this create relies on functionality that was introduced | |
# later than the actual version specified (e.g., when we choose just a major version, but a | |
# method was added after this version). | |
# | |
# This particular check can be difficult to get to succeed as often transitive dependencies may | |
# be incorrectly specified (e.g., a dependency specifies 1.0 but really requires 1.1.5). There | |
# is an alternative flag available -Zdirect-minimal-versions that uses the minimal versions for | |
# direct dependencies of this crate, while selecting the maximal versions for the transitive | |
# dependencies. Alternatively, you can add a line in your Cargo.toml to artificially increase | |
# the minimal dependency, which you do with e.g.: | |
# ```toml | |
# # for minimal-versions | |
# [target.'cfg(any())'.dependencies] | |
# openssl = { version = "0.10.55", optional = true } # needed to allow foo to build with -Zminimal-versions | |
# ``` | |
# The optional = true is necessary in case that dependency isn't otherwise transitively required | |
# by your library, and the target bit is so that this dependency edge never actually affects | |
# Cargo build order. See also | |
# https://github.com/jonhoo/fantoccini/blob/fde336472b712bc7ebf5b4e772023a7ba71b2262/Cargo.toml#L47-L49. | |
# This action is run on ubuntu with the stable toolchain, as it is not expected to fail | |
