Add ARROW_VERSION const to arrow-array - #10957
Merged

Conversation
Expose the crate version the same way the top-level arrow crate does, so dependents that only use arrow-array (e.g. Rust ADBC drivers) can report DriverArrowVersion without invoking cargo metadata at build time.

Rationale for this change
The top-level
arrowcrate already exposesARROW_VERSIONviaenv!("CARGO_PKG_VERSION")(see #6379). Dependents that only usearrow-array(common for Rust ADBC drivers that need a lean dependency set) currently have no equivalent API, so they may need to fall back to invokingcargo metadatain a build script to reportDriverArrowVersion.That approach is fragile for non-Cargo build systems and adds unnecessary clean-build overhead. Exposing the same constant from
arrow-arraymakes version reporting trivial for everyone implementing Rust ADBC drivers (and any other crate that depends onarrow-arraywithout the umbrellaarrowcrate).What changes are included in this PR?
pub const ARROW_VERSION: &str = env!("CARGO_PKG_VERSION")toarrow-array, matching the existing constant on the top-levelarrowcrate.Are there any user-facing changes?
Yes: a new public constant on
arrow-array. No breaking changes.Usage:
