Is there a way to create a rust-polars Series from Vec<u8>?

Question

how to create a Polars Series from Vec<u8> in rust?

use polars::prelude::*;
fn main() {
    let mut col1: Vec<u8> = Vec::new();
    col1.push(1);
    col1.push(2);
    let s1 = Series::new("col1", col1); // error: the trait `polars::prelude::NamedFrom<Vec<u8>, _>` is not implemented for `polars::prelude::Series`
}

Answer 1

Yes, your code works if you enable the dtype-u8 feature like this in Cargo.toml:

polars = { version = "0.26.1", features = ["dtype-u8"] }

The requirement was well hidden in the source code though.
