Getting "the trait arrow2::array::MutableArray is not implemented" error on toy example

[scimas]

Cargo.toml

[package]
name = "rust_testing"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

src/main.rs

use arrow2_convert::ArrowField;

#[derive(ArrowField)]
struct Sample {

On cargo build gives the following error:

What am I missing?

Great question @scimas. Please try with arrow2 0.13:

[dependencies]
arrow2 = "0.13"

I'll look into why it's not working for arrow2 0.14.

[ncpenke]

Opened #65 to track upgrading to arrow2 0.14.

I have a fix and will release a new version shortly so the code you posted should work as-is @scimas. You'll just need to use arrow2_convert = "0.3.1" to point to the new release.

[scimas]

Thank you for the quick turn-around @ncpenke ! But it still does not seem to work. I get two different errors now.

Cargo.toml

[package]
name = "rust_testing"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
arrow2 = "0.14.1"
arrow2_convert = "0.3.1"

Same src/main.rs as before, gives these errors.

I apologize @scimas. I made a mistake when updating the version and there was a mismatch.

Please try again with arrow2_convert = 0.3.2. Thank you.

[scimas]

I don't think 0.3.2 was published to crates.io... or it takes more than 14 hours sometimes for the version to be populated in the index?

[ncpenke]

Apologies @scimas I thought I had pushed it up. I had your test code locally and it built, but turned out the Cargo.lock was still pointing to the old 0.3.1 that had the version mismatch.

It's pushed up now. You may need to remove your Cargo.lock. Please let me know if you run into anymore issues.

[ncpenke]

@scimas Confirmed you'll need to remove your Cargo.lock or run cargo update for this to work in an existing build.

[scimas]

Can confirm everything works fine now, thank you!

[ncpenke]

Solved by publishing and upgrading to arrow2-convert 0.3.2
