Struct genco::js::Import

pub struct Import { /* fields omitted */ }

An imported item in JavaScript.

Created using the import() function.

Implementations

impl Import

pub fn alias<N: Into<ItemStr>>(self, alias: N) -> Self

Alias of an imported item.

If this is set, you'll get an import like:

import {<name> as <alias>} from <module>

Examples

use genco::prelude::*;

let a = js::import("collections", "vec");
let b = js::import("collections", "vec").alias("list");

let toks = quote! {
    #a
    #b
};

assert_eq!(
    vec![
        "import {vec, vec as list} from \"collections\";",
        "",
        "vec",
        "list",
    ],
    toks.to_file_vec().unwrap()
);
