Struct Import

pub struct Import { /* private fields */ }

The import of a JavaScript type 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()?
);

Trait Implementations

impl Clone for Import

fn clone(&self) -> Import

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Import

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> FormatInto<JavaScript> for &'a Import

fn format_into(self, tokens: &mut Tokens<JavaScript>)

Convert the type into tokens in-place.

impl FormatInto<JavaScript> for Import

fn format_into(self, tokens: &mut Tokens<JavaScript>)

Convert the type into tokens in-place.

impl From<Import> for Any

fn from(lang: Import) -> Self

Converts to this type from the input type.

impl Hash for Import

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LangItem<JavaScript> for Import

fn format(&self, out: &mut Formatter<'_>, _: &Config, _: &Format) -> Result

Format the language item appropriately.

impl Ord for Import

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Import

fn eq(&self, other: &Import) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Import

fn partial_cmp(&self, other: &Import) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> Register<JavaScript> for &'a Import

fn register(self, tokens: &mut Tokens<JavaScript>)

Convert the type into tokens.

impl Register<JavaScript> for Import

fn register(self, tokens: &mut Tokens<JavaScript>)

Convert the type into tokens.

impl Eq for Import
