Struct Imports 

pub struct Imports<T>(/* private fields */);

A list of imports.

serde

This type deserializes as a “sequence”.

See: serde data model.

Implementations

impl<T> Imports<T>

pub const fn empty() -> Self

Create a new empty import list.

pub fn len(&self) -> usize

Get the number of imports in the list.

pub fn is_empty(&self) -> bool

Check whether the import list is empty.

pub fn push(&mut self, import: T)

Add import to the import list.

Examples

let mut imports = Imports::empty();
imports.push("module 1");
imports.push("module 2");
imports.push("module 3");

assert_eq!(
    imports.iter().copied().collect::<Vec<_>>(),
    &[
        "module 1",
        "module 2",
        "module 3"
    ]
);

pub fn iter(&self) -> Iter<'_, T>

Get an iterator over the import list.

The iterator visits each import in an unspecified order. Do not rely on the ordering of items.

Example

let mut imports = Imports::empty();
imports.push("module 1");
imports.push("module 2");
imports.push("module 3");

let mut iter = imports.iter();
assert_eq!(iter.next().copied(), Some("module 1"));
assert_eq!(iter.next().copied(), Some("module 2"));
assert_eq!(iter.next().copied(), Some("module 3"));
assert_eq!(iter.next().copied(), None);

Trait Implementations

impl<T: Clone> Clone for Imports<T>

fn clone(&self) -> Imports<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Imports<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Imports<T>

fn default() -> Imports<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Imports<T>

where T: Deserialize<'de>,
