[Question] How to deserialize Vec<Url>

[hh9527]

use url::Url;

#[derive(Debug, Deserialize)]
struct Foo {
    #[serde(with = "url_serde")] // this works
    some_url: Url,

    #[serde(with = "url_serde")] // this does not work
    urls: Vec<Url>
}

You currently can't use with this way; see serde-rs/serde#723.

Support for Vec<Url> probably needs to be added specifically to url_serde, similar to how it supports Option<Url> today.

[SimonSapin]

url 2.0 will support serde 1.x directly (and serializing Vec<Url> should "just work"), without the url_serde crate. Therefore the url_serde crate will likely not get more features.

For anyone else finding this issue via Google, you can enable serde support for urls by enabling the "serde" feature:

url = { version = "2.2.0", features = ["serde"] }
