pub struct StringWithSeparator<Sep>(_);
De/Serialize a delimited collection using Display and FromStr implementation
You can define an arbitrary separator, by specifying a type which implements Separator.
Some common ones, like space and comma are already predefined and you can find them here.
An empty string deserializes as an empty collection.
use serde_with::{CommaSeparator, SpaceSeparator};
use std::collections::BTreeSet;
#[derive(Deserialize, Serialize)]
struct A {
#[serde(with = "serde_with::rust::StringWithSeparator::<SpaceSeparator>")]
tags: Vec<String>,
#[serde(with = "serde_with::rust::StringWithSeparator::<CommaSeparator>")]
more_tags: BTreeSet<String>,
}
let v: A = serde_json::from_str(r##"{
"tags": "#hello #world",
"more_tags": "foo,bar,bar"
}"##).unwrap();
assert_eq!(vec!["#hello", "#world"], v.tags);
assert_eq!(2, v.more_tags.len());
let x = A {
tags: vec!["1".to_string(), "2".to_string(), "3".to_string()],
more_tags: BTreeSet::new(),
};
assert_eq!(r#"{"tags":"1 2 3","more_tags":""}"#, serde_json::to_string(&x).unwrap());
