Macro velcro::linked_list_from

linked_list_from!() { /* proc-macro */ }

An initializer for LinkedList that works the same as linked_list! except that values can be of any type that can be converted into the collection’s item type via an Into implementation.

The type of the item must be known at compile time, and usually this means an explicit type annotation is required.

Usage

use velcro::{linked_list, linked_list_from};

#[derive(Debug, PartialEq, Eq, Hash)]
struct Foo(u64);

impl From<u64> for Foo {
    fn from(other: u64) -> Self {
        Foo(other)
    }
}

let foos: LinkedList<Foo> = linked_list_from![1, 2, Foo(3), ..(4..=6), 7];
assert_eq!(foos, linked_list![Foo(1), Foo(2), Foo(3), Foo(4), Foo(5), Foo(6), Foo(7)]);
