Function from_str_borrowed 

pub fn from_str_borrowed<'input, 'facet, T>(
    input: &'input str,
) -> Result<T, DeserializeError<JsonError>>
where
    T: Facet<'facet>,
    'input: 'facet,

Deserialize a value from a JSON string, allowing zero-copy borrowing.

This variant requires the input to outlive the result ('input: 'facet), enabling zero-copy deserialization of string fields as &str or Cow<str>.

Use this when you need maximum performance and can guarantee the input buffer outlives the deserialized value. For most use cases, prefer from_str which doesn’t have lifetime requirements.

Example

use facet::Facet;
use facet_json::from_str_borrowed;

#[derive(Facet, Debug, PartialEq)]
struct Person<'a> {
    name: &'a str,
    age: u32,
}

let json = r#"{"name": "Alice", "age": 30}"#;
let person: Person = from_str_borrowed(json).unwrap();
assert_eq!(person.name, "Alice");
assert_eq!(person.age, 30);
