join Filter

join can render a list of strings with a separator between each:

extern crate oxiplate;

use oxiplate::prelude::*;

#[derive(Oxiplate)]
#[oxiplate_inline(r#"{{ raw: &values | join(", ") }}"#)]
struct Data<'a> {
    values: Vec<&'a str>,
}

assert_eq!(
    "red, green, blue",
    Data { values: vec!["red", "green", "blue"] }.render()?,
);

Ok::<(), ::core::fmt::Error>(())

{{ raw: &values | join(", ") }}

red, green, blue
