EstablishedShould you depend on aws-smithy-runtime? The data says

Established and steady.

How this verdict is decided (4 rules)
  • Usage: crates.io reverse dependencies (crates that list it as a dependency): 10,000+ = foundational, 1,000+ = widely used, 100+ = established, under 100 = few direct dependents.
  • Direction: the median quiet day in the last 30 days of the window against the first 30, read against the median tracked crate (the whole field moved +39% from late summer to October, so a raw trend says nothing). 10%+ ahead of the field = gaining; 10%+ behind = losing ground; otherwise steady. Steady with no release in 2+ years = quiet for years.
  • Release spikes: the median release-window day against the quiet-day baseline: under 1.15x = no spike, 1.15x to 1.3x = small bumps, 1.3x or more = jumps on release days.
  • Release recency: days since the newest version that was not yanked, from crates.io publish times.
Data: crates.io API, Jul 27, 2026 to Oct 23, 2026, fetched Oct 24, 2026. Downloads are not users: read the baseline as steady use, not a head count.

The numbers in one paragraphaws-smithy-runtime got 43,887,234 crates.io downloads from Jul 27, 2026 to Oct 23, 2026. 18% of them landed within 2 days of one of its 7 releases. On the other 76 quiet days it got a median of 495,308 a day, about 3,467,152 a week. Capping release days at that baseline leaves 42,538,108 release-adjusted downloads for the window.

What this means if you're choosing a dependency

  • Used, not everywhere. 521 crates depend on it. Look at how fast its issues get answered before you lean on it.
  • Actively released. 1.16.1 shipped 5 days ago (Oct 19, 2026).
  • Fit check: license Apache-2.0, edition 2021, needs Rust 1.94.1 or newer (from the latest version's manifest).
  • Compare it by the baseline, not the raw count. 18% of its 43,887,234 downloads in the window landed within 2 days of a release; the steady number is 495,308 a day.

Tracked crates its latest version (1.16.1) depends on (optional ones marked).

What the chart says

  • Weekend quiet days ran at 50% of weekday quiet days (268,481 vs 538,692). A dip that deep is the signature of work-week CI pipelines and developers building on weekdays.
  • Biggest day: 825,817 on Oct 21, 2026, a quiet day with no release nearby.

How we compute this

crates.io counts every download, including CI runners, mirrors and bots that fetch each new version, so raw counts run high (why, in The Manual). We split the last 89 days into release windows (the day a version of aws-smithy-runtime was published, plus the next day) and quiet days, and use the median quiet day as the baseline: an upper bound on steady use, never a head count. The method and data come from our study of 90 days of crates.io data from 69 crates, featured in This Week in Rust #674; check any crate live with the real-downloads checker.
