# facet-value
A memory-efficient dynamic value type for representing structured data, with support for bytes.
## Features
- **Pointer-sized**: `Value` is exactly one pointer in size using tagged pointers
- **Rich type support**: Null, Bool, Number, String, Bytes, Array, Object, DateTime
- **Bidirectional conversion**: Convert between `Value` and any type implementing `Facet`
## Example
```rust
use facet::Facet;
use facet_value::{Value, to_value, from_value};
#[derive(Debug, Facet, PartialEq)]
struct Person {
name: String,
age: u32,
}
// Convert a typed value to a dynamic Value
let person = Person { name: "Alice".into(), age: 30 };
let value: Value = to_value(&person).unwrap();
// Inspect the value dynamically
let obj = value.as_object().unwrap();
assert_eq!(obj.get("name").unwrap().as_string().unwrap().as_str(), "Alice");
// Convert back to a typed value
let person2: Person = from_value(value).unwrap();
assert_eq!(person, person2);
```
