Minimum supported version

  • 1.56.0: 2021 edition
  • 1.59.0: const CStr::from_bytes_with_nul_unchecked (needed by cstr crate, see below)
  • 1.64.0: std::ffi::c_char
  • 1.74.0: Clippy can be configured in Cargo.toml
  • 1.77.0: C string literals, offset_of!

TODO

Before commit:

After commit:

  • lower minimum supported version (Debian needs 1.63.0)
  • Error: Features/Rust/Error
  • QOM: Paolo has started some experiments, Features/Rust/QOM
  • lints:
    • run clippy as part of "make check", possibly only if QEMU is newer than some version (1.74.0 so that clippy can be configured in Cargo.toml?)
    • do not enable groups (complexity, perf, style, suspicious) on regular builds
    • add to CI a fallible job that runs with nightly -Dclippy::complexity -Dclippy::perf -Dclippy::suspicious -Dclippy::style. the job should generally pass, and if a new lint triggers it probably should be added to Cargo.toml.

Possible project targets
