alamb opened a new issue, #2926:
URL: https://github.com/apache/arrow-rs/issues/2926
Reported by @Ted-Jiang in ASF slack
**Describe the bug**
If a user has an outdated Cargo.lock compile may fail:
```
yangjiang@LM-SHC-15009782 arrow-rs % rustup --version
rustup 1.25.1 (bb60b1e89 2022-07-12)
info: This is the version for the rustup toolchain manager, not the rustc
compiler.
info: The currently active `rustc` version is `rustc 1.64.0 (a55dd71d5
2022-09-19)`
yangjiang@LM-SHC-15009782 arrow-rs % cargo test -p parquet
Compiling arrow v25.0.0
(/Users/yangjiang/CLionProjects/github/arrow-rs/arrow)
error[E0599]: no method named `total_cmp` found for struct `f16` in the
current scope
--> arrow/src/datatypes/native.rs:283:22
|
283 | self.total_cmp(&rhs).is_eq()
| ^^^^^^^^^ method not found in `f16`
...
309 | native_type_float_op!(f16, f16::ONE, f16::ZERO);
| ----------------------------------------------- in this macro
invocation
|
= note: this error originates in the macro `native_type_float_op` (in
Nightly builds, run with -Z macro-backtrace for more info)
```
The problem can be solved by `cargo update`
@jhorstmann notes it is likely due to the fact we use half 2.1 features but
only declare half 2.0
**To Reproduce**
not sure
**Expected behavior**
deps are correctly encoded
