EstablishedShould you depend on crossbeam-deque? The data says

Established and steady.

crossbeam-deque: 142 crates depend on it; downloads don't spike on releases.

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 +36% 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 paragraphcrossbeam-deque got 174,240,397 crates.io downloads from Jul 27, 2026 to Oct 23, 2026. 2% of them landed within 2 days of one of its 1 release. On the other 87 quiet days it got a median of 1,924,167 a day, about 13,469,169 a week. Capping release days at that baseline leaves 174,240,397 release-adjusted downloads for the window.

What this means if you're choosing a dependency

  • Used, not everywhere. 142 crates depend on it. Look at how fast its issues get answered before you lean on it.
  • Actively released. 0.8.8 shipped 49 days ago (Sep 5, 2026).
  • Still pre-1.0 (0.8.8). Under Cargo's semver rules a 0.x minor bump may break you, so pin the minor version (crossbeam-deque = "0.8") and read the changelog on upgrades.
  • Fit check: license MIT OR Apache-2.0, edition 2021, needs Rust 1.61 or newer (from the latest version's manifest).
  • Compare it by the baseline, not the raw count. 2% of its 174,240,397 downloads in the window landed within 2 days of a release; the steady number is 1,924,167 a day.

What the chart says

  • Weekend quiet days ran at 60% of weekday quiet days (1,268,051 vs 2,113,998). A dip that deep is the signature of work-week CI pipelines and developers building on weekdays.
  • Biggest day: 3,065,216 on Oct 22, 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 crossbeam-deque 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.
