Function extract

pub fn extract(s: &str, key: &str) -> Result<JsonValue, ExtractError>

Extract a value from a json string without parsing the whole thing.

With the object from benches/json.rs, extract() is ~3.5x faster than json::parse.

Examples

let value = binary_extract::extract(r#"{"foo": "bar"}"#, "foo").unwrap();
assert_eq!(value, "bar");
