[I] Compilation error: ambiguous quarter() method call in temporal.rs with chrono 0.4.41 [arrow-rs]
DataBora opened a new issue, #8221:
URL: https://github.com/apache/arrow-rs/issues/8221
**Describe the bug**
<!--
Compilation fails when using arrow-arith with chrono 0.4.41 due to ambiguous method resolution for `quarter()` in temporal.rs.
-->
**To Reproduce**
<!--
1. Use arrow-arith 53.4.0 or later
2. With chrono 0.4.41
3. Compilation fails with trait ambiguity error
-->
**Error message**
<!--
error[E0034]: multiple applicable items in scope
--> arrow-arith-53.4.0/src/temporal.rs:91:36
|
91 | DatePart::Quarter => |d| d.quarter() as i32,
| ^^^^^^^ multiple quarter found
|
note: candidate #1 is defined in the trait ChronoDateExt
note: candidate #2 is defined in the trait Datelike
-->
**Expected behavior**
<!--
Code should compile without ambiguity errors.
-->
**Proposing solution**
<!--
Disambiguate the method call on line 91 in temporal.rs file:
```rust
DatePart::Quarter => |d| Datelike::quarter(&d) as i32,
-->
