# join_str Simple proc macro to do simple string interpolation as an array join, since it's one of the most efficient methods. ```rust use join_str::jstr; fn main () { let actor_name = "GameROMPlayer"; assert_eq!( String::from("Actor/ActorLink/GameROMPlayer.bxml"), jstr!("Actor/ActorLink/{actor_name}.bxml") ); } ``` If your interpolated code contains quotation marks, pass a raw string to the macro: ```rust use join_str::jstr; use std::collections::HashMap; fn main () { let mut actors: HashMap = HashMap::new(); actors.insert(String::from("GameROMPlayer"), String::from("Link")); assert_eq!( String::from("The GameROMPlayer actor is Link"), jstr!(r#"The GameROMPlayer actor is {actors["GameROMPlayer"]}"#) ); } ```
