Workflow file for this run

.github/workflows/check.yml at 77d3f41
# 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

minimal:
# 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.
