Derive Macro serde_query::DeserializeQuery

#[derive(DeserializeQuery)]
{
    // Attributes available to this derive:
    #[query]
}

Derive macro for DeserializeQuery trait.

Example

use serde_query::{DeserializeQuery, Query};

#[derive(DeserializeQuery)]
struct Data {
    #[query(".commit.authors.[0]")]
    first_author: String,
    #[query(".hash")]
    hash_value: u64,
}

let document = serde_json::to_string(&serde_json::json!({
    "commit": {
        "authors": ["Kou", "Kasumi", "Masaru"],
        "date": "2020-09-10",
    },
    "hash": 0xabcd,
}))?;

// You can use `Query<T>` as a `Deserialize` type for any `Deserializer`
// and convert the result to the desired type using `From`/`Into`.
let data: Data = serde_json::from_str::<Query<Data>>(&document)?.into();

assert_eq!(data.first_author, "Kou");
assert_eq!(data.hash_value, 0xabcd);
