Expand description

Serde space-delimited string deserializer for a Vec<String>.

This function splits a JSON string at each space character into a Vec<String> .

§Example

In example below, the JSON value {"items": "foo bar baz"} would deserialize to:

GroceryBasket {
    items: vec!["foo".to_string(), "bar".to_string(), "baz".to_string()]
};

Note: this example does not compile automatically due to Rust issue #29286.

use serde::Deserialize;

#[derive(Deserialize)]
struct GroceryBasket {
    #[serde(deserialize_with = "helpers::deserialize_space_delimited_vec")]
    items: Vec<String>,
}
