DataStructures.jl vs rlang
A side-by-side editorial comparison of DataStructures.jl and rlang — release velocity, themes, recent moves, and the top alternatives to consider.
DataStructures.jl vs rlang: at a glance
What is DataStructures.jl?
A stable Julia container library coasting on CI and compat housekeeping
DataStructures.jl is in pure maintenance. The three most recent releases contain a CompatHelper bot bump, a CI configuration change, and one release whose notes are nothing but a diff link. No functional change to any container type appears in the visible history.
What is rlang?
rlang moved tidyeval off R's private internals and onto official C API.
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.

A stable Julia container library coasting on CI and compat housekeeping
◆ Current state
DataStructures.jl is in pure maintenance. The three most recent releases contain a CompatHelper bot bump, a CI configuration change, and one release whose notes are nothing but a diff link. No functional change to any container type appears in the visible history.
◆ Where it's heading
This is what a finished, widely-depended-on library looks like: the API is settled and releases exist to keep compat bounds and CI green for downstream packages. Expect the cadence to stay tied to Julia ecosystem housekeeping rather than to feature work.
◆ Prediction
The next releases will most likely be further CompatHelper bumps as new major versions of dependencies land. Nothing in these entries points to planned feature work.
rlang
0.0DEVOPS
rlang moved tidyeval off R's private internals and onto official C API.
◆ Current state
rlang is at 1.3.0, which rewrote hash() to walk objects itself rather than lean on R's serialiser — fixing stability against bytecode and shrinkable vectors, at the cost of invalidating every existing hash value. The release before it closed a multi-year effort: rlang and tidyeval are now fully backed by official C APIs of R, work the notes credit to collaboration with R core.
◆ Where it's heading
The through-line across this whole window is one migration. Release after release retires something that depended on private R internals — env_browse(), env_unlock(), ns_registry_env(), the SEXP iterator now behind a compile flag — and replaces it with sanctioned API. The hash() rewrite in 1.3.0 is the same instinct applied to the serialiser: own the behaviour rather than inherit it.
◆ Prediction
With the C API migration declared complete in 1.2.0, the next releases are likely to be ordinary maintenance and type-checking additions rather than further defunct markings.
