merge_whitespace

此crate包含用于从给定的字符串字面量中删除多个连续空格的过程宏，并用单个空格替换。

示例

以下示例使用可选引号字符来保持引号文本范围不被合并，以及可选转义字符以确保引号字符字面量保持原样。

use merge_whitespace::merge_whitespace;

const QUERY: &str = merge_whitespace!(r#"
     query {
       users (limit: 1, filter: "bought a 12\" vinyl
                                 named \"spaces  in  space \"") {
         id
         name
         todos(order_by: {created_at: desc}, limit: 5) {
           id
           title
         }
       }
     }
     "#,
     quote_char = '"',
     escape_char = '\\');

#[test]
fn test() {
    assert_eq!(QUERY, r#"query { users (limit: 1, filter: "bought a 12\" vinyl
                                 named \"spaces  in  space \"") { id name todos(order_by: {created_at: desc}, limit: 5) { id title } } }"#);
