Rust 1.91.0 was released today: https://blog.rust-lang.org/2025/10/30/Rust-1.91.0/
Per our MSRV policy we can now upgrade from 1.87.0 to 1.88.0:
|
## Rust Version Compatibility Policy |
|
|
|
The Rust toolchain releases are tracked at [Rust Versions](https://releases.rs) and follow |
|
[semantic versioning](https://semver.org/). A Rust toolchain release can be identified |
|
by a version string like `1.80.0`, or more generally `major.minor.patch`. |
|
|
|
DataFusion supports the last 4 stable Rust minor versions released and any such versions released within the last 4 months. |
|
|
|
For example, given the releases `1.78.0`, `1.79.0`, `1.80.0`, `1.80.1` and `1.81.0` DataFusion will support 1.78.0, which is 3 minor versions prior to the most minor recent `1.81`. |
|
|
|
Note: If a Rust hotfix is released for the current MSRV, the MSRV will be updated to the specific minor version that includes all applicable hotfixes preceding other policies. |
|
|
|
DataFusion enforces MSRV policy using a [MSRV CI Check](https://github.com/search?q=repo%3Aapache%2Fdatafusion+rust-version+language%3ATOML+path%3A%2F%5ECargo.toml%2F&type=code) |
Describe the solution you'd like
Bump MSRV here:
|
# Define Minimum Supported Rust Version (MSRV) |
|
rust-version = "1.87.0" |
Include a note in upgrade guide.
Make any changes to codebase (let chains are supported now I believe)
Describe alternatives you've considered
No response
Additional context
Previous bump PR: #17724
Also after this is done I believe we can take on edition 2024: #15804
