Serde json string parse

Provides ParseJson trait and JsonParseError struct which allow parse String or &str types to struct using parse_json_with_data_err trait method.

In case of error JsonParseError contains original String or &str and original parsing error from serde.

Examples

use serde_json_string_parse::{JsonParseError, ParseJson};

#[derive(Deserialize, Debug)]
struct TestStruct {
    key: String,
}

#[rustfmt::skip]
let text = String::from(r#"{
    "key": "value"
}"#);

let parse_result: TestStruct = text
    .parse_json_with_data_err()
    .expect("Parsing failed");
assert_eq!(parse_result.key, "value");

use serde_json_string_parse::{JsonParseError, ParseJson};

#[derive(Deserialize, Debug)]
struct TestStruct {
    key: String,
}

#[rustfmt::skip]
let text = String::from(r#"{
    "key" ___ "value"
}"#);

let parse_error: JsonParseError<String> = text
    .clone()
    .parse_json_with_data_err::<TestStruct>()
    .expect_err("Parsing must fail");

// `original_data` field contains source text
assert_eq!(parse_error.original_data, text);
