Rustc compatibility

Percentage of crates (in their current version) that can be compiled with a given Rust version. The data is based on sampling of cargo check and clippy::incompatible_msrv on Linux/aarch64. Excludes crates that never built (e.g. because they need nightly, or Windows, or unusual C dependencies).

These stats are best-case scenarios that assume use of a most-compatible Cargo.lock file. Fresh projects without a lockfile will be less compatible due to too-new transitive dependencies.

Compatibility weighed by crates' popularity is not a realistic representation of ecosystem-wide compatibility. Actual compatibility is always worse, because MSRV of projects is not an average of their dependencies MSRV, but entirely dependent on their least-compatible dependency.

Usage of Rust versions based on crates.io traffic

This is based on crates.io request log data from the last week. This is not limited to real users, and includes automated traffic like CI. 88% of requests were from stable (non-nightly) Rust versions. Less than 0.16% of requests came from Rust versions older than 1.65.
