Pull Request Overview

This PR implements the ST_Translate() function in Rust, which translates geometry coordinates by fixed X and Y offsets. The implementation leverages the existing CrsTransform infrastructure and includes comprehensive test coverage and benchmarking.

Key changes:

• New ST_Translate() function implementation with support for 2D and 3D geometries
• Integration into the function registry with alphabetically sorted entries
• Test and benchmark coverage for the new functionality

Looks good. Just suggested some optional nits about testing.

[petern48]

optional: A few cases that aren't tested anywhere (in python or rust). I don't think any would fail, but I think some would be nice to test. Particularly non-point geoms, so it's clear it works on them too. Personally, I often look at tests to see how I can use a function when documentation isn't specific enough.

• geometry arg
  • non-empty geometries other than POINT (e.g polygon, multi-*)
  • any M dimension
• dx/dy arg
  • zero or negative
  • integers (inspired by this bug: Casts ints to floats in st_buffer and st_dwithin args #32)
