Struct List

pub struct List<T> {
    pub(crate) items: Vec<T>,
    pub(crate) objects: Vec<Rc<dyn ToBazelDefinition>>,
}

Helper for formatting a list of items.

use cargo_gazelle::{List, QuotedString, ToBazelDefinition};

let deps: List<QuotedString> = List::new(vec![QuotedString::new("tokio")]);
assert_eq!(deps.to_bazel_definition(), "[\"tokio\"]");

Fields

items: Vec<T>

objects: Vec<Rc<dyn ToBazelDefinition>>

Implementations

impl<T> List<T>

pub fn new<E: Into<T>, I: IntoIterator<Item = E>>(items: I) -> Self

pub fn empty() -> Self

pub fn concat_other(self, other: impl ToBazelDefinition + 'static) -> Self

Concatenate another Bazel object to this list.

Concretely this will result in a generated Bazel list like [ ... ] + <concat>.

TODO(parkmcar): This feels a bit off, maybe the API should be something like LinkedList?

pub fn push_front<E: Into<T>>(&mut self, val: E)

Push a value of T to the front of the list.

pub fn push_back<E: Into<T>>(&mut self, val: E)

Push a value of T to the back of the list.

pub fn extend<E: Into<T>, I: IntoIterator<Item = E>>(&mut self, vals: I)

Extend self with the values from vals.

pub fn iter(&self) -> impl Iterator<Item = &T>

Returns an iterator over all of the items.

pub fn is_empty(&self) -> bool

Returns if this List is empty.
