Struct genco::lang::js::Import

pub struct Import { /* fields omitted */ }

An imported JavaScript item import {foo} from "module.js".

Created through the import() function.

Implementations

impl Import

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

Change alias of imported item.

This implies that the import is a named import.

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").with_alias("list");

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

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

pub fn into_default(self) -> Self

Convert into a default import.

Examples

use genco::prelude::*;

let default_vec = js::import("collections", "defaultVec").into_default();

let toks = quote!(#default_vec);

assert_eq!(
    vec![
        "import defaultVec from \"collections\";",
        "",
        "defaultVec",
    ],
    toks.to_file_vec()?
);

pub fn into_wildcard(self) -> Self

Convert into a wildcard import.

Examples

use genco::prelude::*;

let all = js::import("collections", "all").into_wildcard();

let toks = quote!(#all);

assert_eq!(
    vec![
        "import * as all from \"collections\";",
        "",
        "all",
    ],
    toks.to_file_vec()?
);

impl Ord for Import

fn cmp(&self, other: &Import) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.
