defmt-rtt
Counted from the Cargo.toml manifests of the 25 indexed repositories that declare defmt-rtt as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in defmt-rtt projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of defmt-rtt projects that also use it.
